Baby Essentials Checklist

The baby product market is designed to make everything feel essential. This checklist is built around a different question — not what could be useful, but what you genuinely need in the first 90 days to keep your baby safe, healthy, and comfortable.

Most parents overbuy by hundreds of dollars before their baby arrives. This checklist stops that.

The baby product market is engineered to make everything feel essential. It isn't. This checklist identifies what you genuinely need in the first 90 days — and names what to skip, and why, so you spend where it actually matters.

Work through this before you buy anything. The picks are what we'd choose.

Before the checklist

Why most baby buying lists set parents up to overspend

The average first-time parent spends significantly more than they need to in the months before birth. A significant portion goes toward products that either never get used or get replaced within the first month once actual routines become clear.

The most useful framework is to separate purchases into three tiers: things you need before the baby arrives, things you can buy in the first two weeks once you know what you're dealing with, and things that can wait until a genuine need emerges. Most registry lists collapse all three into one. This checklist focuses on Tier 1 only.

Overspending traps to identify early

Wipe warmers. Bottle sterilisers that duplicate a dishwasher. Elaborate sound machines with app connectivity when a simple fan would do the same job. Baby shoes for infants who cannot walk. None of this is harmful — but it represents real money spent before you know what your specific baby actually needs.

Part 1 of 3 — Safe sleep basics

Safe sleep basics

Firm, flat sleep surface — crib, bassinet, or play yard — that meets ASTM safety standards
The AAP recommends a firm, flat sleep surface in a safety-approved sleep environment. The surface should be firm enough to pass the hand-press test — press down firmly and it springs back immediately with no indent.
Fitted sheet is the only item in the sleep space
No pillows, bumpers, positioners, or loose bedding. The AAP is explicit: a fitted sheet is the only item that belongs in the infant sleep space.
Sleep space is in the parent's room for the first 6 months
The AAP recommends room-sharing without bed-sharing for at least the first 6 months. A bassinet or co-sleeper within arm's reach is the recommended arrangement.
Sleep environment is free of smoke — including secondhand smoke
The AAP identifies smoke exposure as a significant risk factor in infant sleep safety. This includes secondhand smoke from any source.
All adults in the household are familiar with current AAP safe sleep guidelines
Safe sleep practice requires consistent application by all caregivers. Review the current AAP guidelines with anyone who will be responsible for the baby's sleep. AAP safe sleep guidelines
Part 2 of 3 — Daily care essentials

Daily care essentials

Infant car seat is installed and inspected before the due date
A car seat inspection by a certified Child Passenger Safety Technician (CPST) confirms correct installation. Many fire stations and hospitals offer this service free of charge. NHTSA car seat inspection locator
Feeding supplies match the intended feeding method
For breastfeeding: nursing bra, nipple cream, breast pads. For formula feeding: bottles, formula, and a bottle brush. Do not over-purchase bottle types before knowing what the baby will accept.
Nappy changing supplies are stocked for the first 2 weeks
Newborns use 10–12 nappies per day in the first weeks. Stock for 2 weeks before purchasing additional supplies — this avoids over-investing in a size or brand before you know what works.
Bathing supplies are limited to essentials — bath tub, washcloths, mild soap
A purpose-built infant bath tub is the safest option for the first months. Fragrance-free, dye-free soap and a soft washcloth are all that is needed. Elaborate bath sets are not required.
Baby clothing is sized for actual birth weight, not 0–3 month average
Newborn sizing varies significantly by brand and by baby. Stock a limited quantity of newborn size and plan to purchase additional sizes once the baby's growth rate is clear.
Part 3 of 3 — Health and monitoring

Health and monitoring

Rectal thermometer is available — the only accurate method for infants under 3 months
The AAP recommends rectal temperature measurement for infants under 3 months. Temporal, axillary, and ear thermometers are not reliable for this age group.
Nasal aspirator is available — manual or electric
Infants cannot blow their nose. A nasal aspirator is a genuine first-90-days essential, particularly during cold and flu season. The NoseFrida-style manual aspirator is as effective as electric alternatives.
Pediatric contact information is confirmed and accessible to all caregivers
Confirm the pediatrician's contact details, after-hours line, and nearest emergency facility before the baby arrives. Make this information visible to all caregivers.
Baby monitor is set up and tested before the due date
Test signal range, night vision, and battery life before the baby arrives. See the Baby Monitor Checklist for full evaluation criteria.
Poison control number is posted visibly: 1-800-222-1222 (US)
Post the national poison control number visibly in the kitchen and near any medication storage area. US Poison Control Center
What to skip in the first 90 days

What to skip

Common purchases that can wait

High chairs (needed at 4–6 months), baby bouncers and swings (useful but not essential — wait to see if your baby responds to them), bottle warmers (a bowl of warm water works as well), elaborate nursery décor that does not affect safety or function, and any product designed to help the baby sleep in a non-AAP-approved position.

5 vetted picks

Our picks — what we'd actually buy

Safe sleep
Halo Bassinest Swivel Sleeper
Best for: room-sharing safe sleep within arm's reach of parent
Meets ASTM safe sleep standards. Swivels 360 degrees to allow easy reach from bed. Side wall lowers for night feeds. Firm, flat sleep surface. Suitable from birth to approximately 20lbs or until the infant begins to push up on hands and knees.
Trade-off: Does not function as a long-term sleep solution — transition to a crib when the baby reaches the weight limit or developmental milestone. Verify current ASTM compliance before purchase.

Feeding
Medela Harmony Manual Breast Pump
Best for: reliable manual pumping for occasional or supplemental use
BPA-free. 2-Phase Expression technology mirrors natural infant nursing pattern. Compact and travel-friendly. Does not require power or charging. Recommended by the AAP as appropriate for occasional use alongside breastfeeding.
Trade-off: Manual operation is not practical for exclusive pumping — for full-time pumping, a hospital-grade electric pump is more appropriate.

Health
Frida Baby NoseFrida Nasal Aspirator
Best for: effective infant nasal clearing without electric complexity
No battery or charging required. Replaceable hygiene filter prevents any nasal secretion from reaching the parent's mouth. More effective than bulb syringes at clearing infant nasal passages. Easy to disassemble and clean.
Trade-off: Requires practice to use effectively — read the instructions and watch the demonstration video before first use.

Monitoring
Braun ThermoScan 7 Ear Thermometer
Best for: reliable temperature measurement for infants over 3 months
Clinically validated accuracy. Age-based illumination system indicates normal, elevated, or high temperature by colour. For infants under 3 months, use a rectal thermometer — this is an AAP recommendation, not a product limitation.
Trade-off: Ear thermometers are not reliable for infants under 3 months due to ear canal anatomy. A rectal thermometer is required for the newborn period — this pick is for use from 3 months onwards.

Bath
Summer Infant My Bath Seat
Best for: supported infant bathing with stable base
Provides a stable, supported bathing position for infants who can sit with support (approximately 6 months). Non-slip base. Easy to clean. Folds for storage.
Trade-off: This is not suitable for newborns — newborns require a reclined infant bath tub. This pick is appropriate for the 6-month+ transition to upright supported bathing.
