When to Buy Baby Gear: A Month-by-Month Timeline for New Parents
The Problem With Buying Everything at Once
Most first-time parents make the same mistake: they spend weeks researching every product, buy everything before the baby arrives, and then discover half of it isn't needed. The expensive swing sits unused. The nursing pillow is the wrong shape. The stroller they love is too wide for their building elevator.
The smarter approach: buy in stages, buy secondhand where possible, and don't buy anything your baby actually tells you they don't need. Here's a timeline that works.
Months 1–3 of Pregnancy: Research Phase Only
Don't buy anything yet. Your priorities right now:
- Research stroller brands. This is the biggest decision and the longest lead time. Read reviews, go to a baby store and push a few, figure out what matters to you (lightweight vs. rugged, compact vs. full-size, single vs. double-ready).
- Join local parent groups. Nextdoor, Facebook neighborhood groups, and platforms like Nestling often have gear recommendations from parents in your specific area. What works in a suburb doesn't always work in a city.
- Set a realistic budget. The average US family spends $6,000–$10,000 on baby gear in the first year. Buying secondhand cuts this in half or more.
Months 4–5: Start With the Big Items
Car seat and stroller should be bought now — these require the most research and are the items you'll use from day one.
Car Seat (Month 4)
You need an infant car seat before you leave the hospital. Research starts now. Popular options:
- Chicco KeyFit 35: Most recommended by pediatricians. Easy install, compatible with many strollers, solid safety record.
- Nuna PIPA Lite: Lightest infant car seat available. Worth it if you'll carry baby in it a lot.
- UPPAbaby Mesa V2: Best if you already have or plan to buy an UPPAbaby stroller.
Buy new or from someone you know. Used car seats require verified history. See our guide on used car seat safety.
Stroller (Month 4–5)
Once you've decided on a stroller, start watching for secondhand listings. Good strollers on Nestling move quickly, so finding the right one can take a few weeks.
If you're planning to use the stroller with your infant car seat in travel-system mode, confirm compatibility with an adapter before buying secondhand.
Month 6: Nursery Setup
Start the nursery now — not because baby needs the room immediately (most newborns sleep in a bassinet in your room for 3–6 months) but because nursery furniture takes time to source, ships slowly, or needs assembly.
Crib: One of the best secondhand buys available. Cribs are built to be durable, barely wear out, and are thoroughly used by parents who are careful about safety. Look for:
- JPMA-certified
- No drop-side mechanism (banned since 2011)
- All hardware present
- Mattress sold separately
Dresser/changing table: Perfect secondhand buy. IKEA Hemnes, IKEA Sundvik, and Pottery Barn dresser units are extremely common on secondhand marketplaces and hold up well. Buy a changing pad + cover separately.
Monitor: Research now, buy secondhand or new in month 7. Popular: Nanit Pro (camera-based with breathing monitoring), Owlet Dream Duo (sock + camera). These are fine to buy used — just factory reset.
Month 7: Feeding and Sleep
Bassinet / Co-sleeper
Most newborns sleep in your room for the first 3–6 months. Bassinets and co-sleepers are fine to buy secondhand — just verify the mattress is included and not compressed, and that it's not recalled.
Popular: SNOO Smart Sleeper (expensive new, significant savings used), Halo Bassinest, 4moms Mamaroo Sleep.
Feeding Setup
This one depends entirely on your plans.
If breastfeeding:
- Breast pump: covered by most insurance, so get yours free through insurance before buying anything
- Nursing pillow: Boppy and My Brest Friend are fine secondhand — just wash the cover
- Milk storage bags: buy new
If formula feeding:
- Bottles: Buy new. Plastic degrades, and secondhand nipples are a hygiene risk.
- Bottle warmer: Great secondhand buy.
- Baby Brezza formula maker: Great secondhand buy — resets easily.
High Chair
Do NOT buy this now — you won't need it for 4–6 months after birth. Wait until you're a few months in, see how your baby is growing, and buy then. Popular: Stokke Tripp Trapp, IKEA Antilop, Graco Blossom. All are excellent secondhand buys.
Month 8: Clothing and Miscellaneous
Clothing
Buy the minimum in newborn size — many babies skip it entirely. Stock sizes 0–3M and 3–6M. Buy secondhand; babies outgrow clothes in weeks. You'll need:
- 7–10 onesies per size
- 5–7 sleepers
- A few warmer layers depending on season
- Socks
Everything else is optional. Don't buy shoes. Babies don't need shoes.
Car and Travel
- Car mirror: Buy new ($15–$20). Not worth hunting secondhand.
- Infant insert for car seat: Usually included with seat — confirm when buying.
- Diaper bag: Fine secondhand. Popular: Kibou, Skip Hop, Fawn Design.
After Baby Arrives: Buy These Based on Your Baby
Every baby is different. Wait until you know yours before buying:
- Swing / bouncer: Some babies love them; some don't care. Buy used after birth when you know what your baby responds to. Common: 4moms mamaRoo, Fisher-Price Snugabunny.
- Baby carrier: Same — fit and preference vary enormously. Try a few at a carrier library or borrow before buying. Options: Ergobaby Omni 360, BabyBjörn One, Solly Baby wrap.
- Baby gym / activity mat: Wait until 2–3 months when baby actually interacts with it.
- Exersaucer / jumper: Wait until 4–6 months.
- Convertible car seat: You'll need one when the infant seat is outgrown, typically around 9–12 months. Buy closer to that time.
What to Never Buy (New or Used)
- Crib bumpers: Banned for safety reasons. Don't buy them.
- Used breast pump: Hygiene risk even with new parts on older closed-system pumps. Get one free from your insurance.
- A used sleep positioner or wedge: Safety hazard; not recommended by pediatricians.
- Baby shoes before walking: You'll waste money on multiple sizes before they need them.
