It’s not about stocking up on everything like with your first. it’s more about smart, intentional purchases that truly support your growing family and make daily life a bit smoother. This guide will walk you through what’s worth buying, what you can probably skip, and how to prepare your home and your other children for the newest arrival.

The “Do I Really Need That?” Question: Assessing Your Existing Gear

When baby number three is on the way, the first thing I always tell parents is to take a deep breath and look at what you already have. You’re not starting from scratch, which is a huge advantage! You’ve got years of baby gear history in your house, but it’s crucial to figure out what’s still good to go and what needs to be replaced.

Taking Inventory: What You Already Have

Go through all your baby boxes and pull out everything. Think about items like baby swings, bouncers, play mats, and even smaller things like burp cloths and bottles. For your first and second, you might have bought a ton of gear, but now you know what really worked for your family and what just collected dust. If something was a lifesaver for your previous two, chances are it will be for your third too. Don’t feel pressured to buy all new stuff just because it’s a new baby!

Wear and Tear: When to Replace

you’ve got a pile of stuff. Now comes the critical part: inspecting it. Look for any broken parts, rips, or excessive wear. For soft goods like blankets, clothes, or fabric inserts for bouncers, consider if they’re still in good condition or if they’re just too stained or worn out. Sometimes, a good deep clean is all they need, but sometimes, it’s just time to let go.

Remember, less can be more, especially with baby clothes. Your third baby might wear the same outfits on repeat for weeks, so don’t overdo it with a massive new wardrobe if you have plenty of hand-me-downs. However, a few fresh, new newborn outfits can be a lovely touch to make this baby feel special. What to Buy for Tacos: Your Ultimate Shopping Guide for an Epic Taco Night!

Safety First: Car Seats and Cribs

This is where you absolutely cannot compromise. Car seats have expiration dates, typically ranging from 6 to 10 years from the date of manufacture. You’ll find this date on a label on the seat itself. Even if a car seat looks perfectly fine, the materials can degrade over time, making it unsafe. Also, if any of your car seats have been in an accident, they need to be replaced, even a minor fender bender. Safety standards for car seats also get updated. For instance, as of June 30, 2025, new harnessed car seats will need to pass stricter side-impact crash tests, which will affect weight limits for infant and forward-facing seats. So, check the manufacturing date and any recalls, and be prepared to buy a new infant car seat or convertible car seat if your old one is expired or doesn’t meet current safety guidelines.

For cribs, inspect them thoroughly for loose slats, splintering wood, or any signs of damage. Make sure they meet current safety standards – older cribs might have features that are no longer considered safe, like drop sides. If your crib is sturdy and meets all current safety regulations, you’re likely good to reuse it!

Big Ticket Items You Might Actually Need

Even if you’re reusing a lot, there are a few big-ticket items that often need an upgrade or replacement with a third child. These are typically the items that accommodate multiple children or have strict safety guidelines.

Double or Triple Strollers: The Essential Upgrade

this one is huge. With two older kids and a newborn, your single stroller just isn’t going to cut it, and even a double might not be enough depending on the ages of your older children. Many parents find themselves needing a stroller for three. This could be a double stroller with a ride-along board for an older sibling, or even a dedicated triple stroller.

You’ve got options:

  • Tandem Strollers: These often have seats in front and back, or stack on top, allowing for a more narrow footprint, which is great for navigating crowded places. Brands like the UPPAbaby Vista V3 with a riding scooter or the Cybex Gazelle S which can convert from single to double with 20+ configurations are popular choices. The Silver Cross Wave 3 is also great, often coming with two seats and a bassinet, making it super versatile.
  • Side-by-Side Strollers: These offer equal views for both seated children and are often easier to maneuver. Some, like the Valco Baby Snap Duo Trend, can even add a kickstand for a third sibling. The Bugaboo Donkey5 is another standout, praised for its smooth ride even with three children.
  • Stroller Wagons: These are becoming increasingly popular for families with multiple children because they offer flexible seating and large storage capacity. Some models can fit three or even four children comfortably.
  • Convertible Strollers with Add-ons: Many popular double strollers, like the Baby Jogger City Select 2 or Joovy Qool, can be configured for three kids by adding a second seat, a bassinet, or a glider board for an older child to stand on.

Consider how you’ll use it – will you be walking a lot, or mostly using it for quick trips? Your lifestyle will heavily influence the best choice for your family.

Cribs and Sleeping Arrangements: Space Solutions

Sleeping arrangements can get tricky with a third baby, especially if your older kids still occupy their own rooms. You might need another crib, or you might look for more compact solutions.

  • Mini Cribs: If space is tight, a mini crib is a fantastic option. They’re smaller than standard cribs typically 36-40 inches long versus 52 inches and many are foldable or on wheels, making them easy to move around your home. The Babyletto Origami Mini Portable Crib or the Dream On Me Aden 4-in-1 Mini Convertible Crib are great choices that offer both portability and functionality.
  • Bassinets: A bassinet for the first few months is often a good idea, especially for room-sharing. Some parents love smart bassinets like the SNOO for better sleep, while others prefer portable options like a Moses basket bassinet for daytime naps around the house.
  • Crib Mattresses: Even if you’re reusing a crib, consider a new crib mattress for safety and hygiene. Many modern mattresses offer features like breathability and non-toxic materials, which are worth investing in.

Car Seats: Safety for Three

As we talked about, car seats are non-negotiable for safety. When you’re fitting three car seats across, especially in a standard vehicle, narrow-profile car seats become your best friend. Look for brands and models known for being slim. Some popular choices that work well for three-across installations include the Clek Foonf or Fllo convertible car seats, or the Britax One4Life Slim All-In-One.

  • Infant Car Seats: These are rear-facing only and are great for newborns as they’re portable. The Nuna Pipa RX and Britax Willow S are highly rated options.
  • Convertible Car Seats: These can be used rear-facing for longer and then converted to forward-facing. They’re a long-term investment. The Graco 4Ever DLX is a popular convertible seat.
  • Booster Seats: For your older children who have outgrown a harnessed seat but still need a boost for proper seatbelt fit.

Always check the height and weight limits for each seat and ensure it fits properly in your vehicle. Some vehicles are better suited for three-across installations, like certain minivans and larger SUVs, but it can be done in many cars with the right narrow seats. The most important thing is that the car seat fits the child, fits the car, and you can install and use it correctly every single time.

Everyday Essentials: Replenishing and Upgrading

You’ve probably got a good handle on the day-to-day items from your previous babies, but there are always things that need replenishing or a slight upgrade for a third.

Diapering Dilemmas: Stocking Up Smart

Diapers and wipes are constant consumables, and you’ll go through a ton of them. This is one area where you can definitely stock up, especially if you catch a sale. Consider buying diapers in various sizes size 1 is a good bet if you’re unsure of newborn size and don’t forget the baby wipes. If you’re into cloth diapering, you might need a refresh on covers or prefolds. A good diaper pail that actually keeps the stink contained like the Ubbi is also a lifesaver.

Feeding the New Arrival: Bottles, Breastfeeding, and Beyond

Whether you’re breastfeeding, formula feeding, or a combination, you’ll need feeding supplies. Your Ultimate Road Trip Checklist: Everything You Need to Hit the Road Right

  • Bottles: Your older kids might have preferred certain bottles, but remember every baby is different! It’s a good idea to have a few different brands of baby bottles on hand like Dr. Brown’s or Comotomo to see what your new baby likes.
  • Breastfeeding Supplies: If you’re breastfeeding, ensure your breast pump is still in good working order and check for any replacement parts like tubing or flanges. Nursing bras, nipple cream, and milk storage bags are also essential.
  • High Chair: You might already have one, but if your older children are still using theirs, or if it’s seen better days, a new high chair might be necessary. Some parents opt for portable booster seats or clip-on chairs for smaller spaces.

Clothing Considerations: Hand-Me-Downs vs. New Basics

Hand-me-downs are a blessing for a third baby, saving you a ton of money! However, it’s nice to have a few new items just for your new arrival. Focus on practical, easy-to-manage clothing:

  • Onesies with Zippers: Seriously, zippers are life for those middle-of-the-night changes!
  • Swaddles: You can never have too many swaddle blankets. They double as burp cloths, nursing covers, and changing pads. Velcro swaddles like the HALO SleepSack are often highly recommended for secure swaddling.
  • Socks and Booties: Baby socks have a mysterious way of disappearing, so stocking up on a fresh batch is always a good idea. Snap or Velcro booties are great for keeping tiny feet warm in colder months.

Bath Time and Health: Fresh Supplies

Your older kids’ bath toys might still be around, but it’s good to refresh some personal care items.

  • Infant Bathtub: A dedicated infant bathtub or bath support can make bath time much easier and safer, especially with two other kids to manage.
  • Baby Wash and Lotion: While you might have some leftover, it’s a good time to get new, sensitive-skin friendly baby wash and lotion.
  • Medicine Kit: Stock up on baby essentials like infant pain relievers, gas drops, diaper rash cream, and a nose aspirator like the FridaBaby NoseFrida. You’ll thank yourself for having these on hand when you need them at 2 AM.

Making Life Easier: Smart Buys for a Third Baby

With two other children, your life is already a whirlwind. The goal for baby number three is to simplify wherever possible. These items aren’t always “essentials” but they can be game-changers for your daily routine.

Baby Carriers and Wraps: Hands-Free Parenting

Being hands-free is a must with three kids! A good baby carrier or wrap allows you to snuggle your newborn while still being able to chase after your older two, cook dinner, or simply get things done around the house. Many parents love soft wraps like the Solly Baby wrap for newborns and then transition to more structured carriers like the Baby Bjorn as baby gets older.

Bouncers, Swings, and Play Mats: Keeping Baby Content

Having safe, comfortable places to put your baby down is crucial. While you might have these from previous children, they often get a lot of use and might need replacing.

  • Bouncers and Swings: These can provide a few precious moments of hands-free time. Many parents swear by the Baby Bjorn Bouncer for its simplicity and baby’s enjoyment.
  • Play Mats and Activity Gyms: A clean, engaging play mat gives your baby a stimulating space for tummy time and independent play.

Organization Solutions: Taming the Chaos

Three kids mean three times the stuff! Good organization is key to maintaining some semblance of order.

  • Newborn Cart: A rolling utility cart stocked with diapers, wipes, burp cloths, a few outfits, and nursing/feeding supplies can be a lifesaver. You can wheel it from room to room, keeping essentials close by without having to trek to the nursery every time.
  • Storage Bins: Invest in more storage bins for clothes, toys, and baby gear. Labeling them makes it easier to find things and keeps clutter at bay.
  • Diaper Bag: Your old diaper bag might be worn out, or you might need something bigger or more versatile. Many parents opt for a diaper backpack for hands-free convenience, or a stylish tote that doesn’t scream “baby bag”.

Meal Prep and Convenience Foods: Saving Time

This isn’t baby gear, but it’s a huge “buy” for a third baby. Your time will be even more stretched, so anything that simplifies mealtime is worth it. Stock your freezer with easy-to-reheat meals before the baby arrives. Look into healthy pre-made meal services or just simple, quick-cooking pantry staples. Having a well-stocked kitchen with minimal effort will be a huge relief.

Gifts for the Third Baby: What to Ask For or Give!

When it comes to gifts for a third baby, most families have accumulated a lot of gear. So, instead of another onesie, think practical, consumable, or sentimental.

Practical Gifts: Consumables and Services

These are the gifts that experienced parents truly appreciate because they directly reduce stress and daily chores. What to Buy for Mosquito Bites: Your Ultimate Guide to Stopping the Itch

  • Diapers and Wipes: Seriously, you can never have enough! Gift cards for these are also gold.
  • Meal Delivery/Gift Cards for Food: Meals are often the most appreciated gift. Gift cards to local restaurants or meal delivery services mean less cooking during the newborn haze.
  • Housekeeping or Laundry Service: A few sessions of professional cleaning or laundry can feel like a luxury that makes a huge difference.
  • Postpartum Basket: Curate a basket with favorite postpartum recovery items for the mother like a nice body wash, comfortable socks, healthy snacks.
  • Coffee! Many experienced parents find coffee a necessity to keep up with multiple kids. A giant bag of their favorite roast or a gift card to a coffee shop is always a hit.

Sentimental Gifts: Personalized Touches

While hand-me-downs are practical, every baby deserves something special that’s just for them.

  • Personalized Items: A blanket, a special outfit, or a wooden baby block with their name and birth stats are wonderful keepsakes.
  • Baby Memory Book: This is a beautiful way to document their first year, especially if you didn’t get around to it with previous children.
  • Professional Photography Session: Capture those fleeting newborn moments and precious sibling interactions.

Gifts for the Older Siblings: Easing the Transition

Don’t forget the big brothers and sisters! A new baby is a huge adjustment for them, and a special gift from the “new baby” can help them feel included and excited.

  • Baby Doll or Doll Carrier: This allows older siblings to mimic caring for the new baby and feel like a helper.
  • Kids’ Camera: Empower them to capture their own memories of the new family member.
  • “Big Sibling” Books: Books about becoming an older brother or sister can help them understand and process the changes.
  • Matching Pajamas: Adorable matching PJs for all the siblings can make for sweet photos and a sense of unity.
  • Special Outing or One-on-One Time: A “date” with a parent can reassure older children that they’re still loved and important.

Budgeting for Baby Number Three: Smart Saving Tips

Bringing a third child into the family definitely adds to the budget, but you’ll find there are often “economies of scale.” What does that mean? Basically, the cost of raising a third child is generally less than the first, because you already have so much stuff! On average, the annual cost of a third child is about $16,513, compared to $20,814 for the first, according to a 2023 study. Still, total costs for raising three children to age 18 can be well over $1 million. So, smart budgeting is still important.

Secondhand Savvy: Where to Find Deals

This is your superpower now! You know what’s worth buying new and what you can get gently used.

  • Online Marketplaces: Local parent groups on social media, online consignment shops, or apps are treasure troves for gently used baby gear. You can find everything from clothes and toys to bouncers and even strollers in excellent condition.
  • Consignment Sales & Stores: Many communities have seasonal consignment sales where you can find high-quality used items at a fraction of the cost.
  • Garage Sales/Charity Shops: Keep an eye out for these. You can score amazing deals on clothing and toys.

Always remember safety when buying secondhand, especially for items like car seats which should always be new unless you know the history and expiration date and cribs ensure they meet current safety standards. What to Buy for Law School: Your Ultimate Toolkit for Success

Borrowing and Swapping: Community Resources

Don’t be shy about asking friends and family if they have items they’re no longer using. Many parents are happy to lend or pass on baby gear.

  • Parent Networks: Tap into your network of fellow parents. You might be surprised by what’s available for free or a small fee.
  • Toy Libraries: Some communities have toy libraries where you can borrow toys, saving money and reducing clutter.

Sales and Discounts: Timing Your Purchases

You’ve got a bit more lead time now, so you can be strategic with your purchases.

  • Seasonal Sales: Keep an eye out for major sales events throughout the year e.g., end-of-season clearances, holiday sales.
  • Baby Events: Many large retailers have baby-specific sales events or even baby expos that offer discounts on essential gear.
  • Register for Discounts: Even if you’re not having a traditional baby shower, creating an Amazon Baby Registry can give you access to completion discounts, which can be useful for those bigger items you do need to buy new.
