The real recurring costs
Gear gets the attention, but consumables are the budget. Roughly, per month:
- Diapers & wipes: $70–90 — a newborn goes through 8–12 diapers a day. Run your own numbers with the diaper cost calculator; brand choice alone swings this by $30+/month.
- Formula (if used): $150–300 — the widest-swinging line item. Store-brand formula meets identical FDA standards as name brands; the formula calculator shows your true monthly cost across powder, concentrate, and ready-to-feed.
- Clothes: $30–50 averaged — babies change sizes seven times in year one, which is why buying ahead at full price is a trap (see the sizes guide).
- Childcare — if you need it, it dwarfs everything else combined. Price it before the baby arrives, not after.
Where spending less is actually better
- Clothes. Worn for six weeks, outgrown, often never stained once. Secondhand and hand-me-downs are functionally new.
- Toys, bouncers, swings. Your baby will prefer the remote control anyway. Buy used, or borrow — half of babies hate the swing and you want to find out for $15, not $180.
- The bassinet. Used for 3–6 months, total. Borrow one, or skip straight to a crib in your room.
- Maternity and nursing wear. The resale market is enormous precisely because everything is barely worn.
- The wipe warmer, bottle sterilizer, diaper genie refills, changing table. A regular trash can with a lid, hot soapy water, and a dresser top do the same jobs.
The only category to never buy used: the car seat. Crash history is invisible, plastic degrades, and seats expire. Buy new, even the budget model — every seat sold in the US passes the same federal crash standards. A $90 seat installed correctly beats a $500 seat installed wrong.
Where spending more pays off
- The crib mattress — firmness is a safety feature, and it's in use for years.
- One great carrier — the difference between "baby naps on me while I live my life" and "I'm trapped on the couch."
- The stroller you'll actually push daily. Match it to your life, not the reviews — the stroller quiz gets you there in six questions.
- A good breast pump if pumping — but check insurance first; most US plans cover one free.
The 60-second budget plan
- Plan the nursery with the nursery budget planner — pick your tier before you shop.
- Registry: put the consumables and big-ticket items on it (diapers, wipes, car seat, stroller). Let gift-givers fund the expensive stuff instead of buying you 12 newborn outfits.
- Buy clothes and toys secondhand; buy the car seat and mattress new.
- Delay everything delayable — high chair, size 3 diapers, baby-proofing gear. Future-you knows more.
