Boys · Newborn (0–3 months)

The first three months with a baby boy are measured in diaper changes, and this collection is stocked accordingly. The backbone is 3-pack short-sleeve bodysuits in rocket, stripe, tool-bench, and slogan prints - coordinated multi-packs that make the diaper-bag math simple, because any spare bodysuit already matches whatever he is wearing. Around those packs sit two-piece cotton outfits that pair a snap-crotch romper with soft pull-on pants, plus bodysuit-and-shorts sets for warmer weeks. Every listing is sized by age in months with EU height in centimeters, so you match your baby to a measurement instead of guessing. Compared with a big-box newborn wall, this is a tighter, more playful edit: the prints lean fun and boyish rather than pastel filler, and nearly everything opens fully at the crotch so 2 a.m. changes stay quick. If you are building his first wardrobe, start with two or three bodysuit packs for daily wear, add a couple of complete outfits for outings and photos, and wash a few 3-6 month pieces early - many boys outgrow 0-3 months faster than parents expect.

How to choose

• Count the snaps: full crotch snaps on bodysuits and rompers are the difference between a ten-second change and a wrestling match - at eight to ten changes a day, they matter more than any print.
• Multi-packs first, outfits second: bodysuit 3-packs absorb the everyday mess; one or two romper-and-pants sets cover visits, photos, and going home from the hospital.
• Buy the next size before you need it: keep a few 3-6 month pieces washed and ready so a growth spurt never means a too-tight onesie morning.
• Short sleeves work year-round: alone in summer, and as the base layer under pants and warmer pieces in winter, so packs stay useful across seasons.

FAQ

What size does a newborn baby boy wear?

Sizes here run by age in months with EU height in centimeters on each listing. Match your baby to the centimeter height rather than the age label, and when he sits between sizes, take the larger one - roomy lasts longer and is easier to dress.

How many clothes does a baby boy need for the first three months?

A practical baseline is 5-7 bodysuits plus 2-3 complete outfits per size. Multi-packs get you there in two or three purchases without overbuying a size he will only wear for weeks.

Do these work as a baby shower gift?

Yes - a bodysuit pack in a fun print plus a romper set is a gift that actually gets worn. Sizing by month makes it easy to give the 3-6 month size so it is useful after the newborn pile runs out.
