What Size Baby Clothes Should I Buy Before Birth
Share
Buy a small mix of newborn and 0–3 month clothes before birth instead of committing to one size. Babies and brands vary, so the goal is a flexible first rotation—not predicting the full wardrobe in advance.
Buy a practical small newborn set
Most families like to have a few newborn-size basics ready for the early days. Soft bodysuits, a few easy outfits, and simple extras usually matter more than buying a large stack.
Add some 0-3 month pieces early too
Parents often feel more prepared when the next size is already in the drawer. A small backup group in 0-3 months helps the transition feel easier once newborn pieces start to fit less comfortably.
Focus on fast-use categories first
The most useful sizes are often the ones in pieces baby wears repeatedly, such as bodysuits and other soft basics. A practical wardrobe grows from the most-used items outward.
Avoid building the full wardrobe before baby arrives
It is common to overbuy out of excitement or uncertainty. Many parents end up preferring a smaller starter set and adding more once they understand baby’s size and routine.
Keep the goal simple
Buying before birth does not need to feel like solving everything in advance. It is enough to start with a small, gentle wardrobe that gives you flexibility in the first weeks. Petit Hollow supports that kind of calmer start with soft basics that are easy to build around.
FAQ
Should I buy newborn or 0–3 month clothes?
Buy a small mix of both. That is more flexible than committing the full starter wardrobe to one size before you know how each piece fits.
How much should I buy in each starter size?
Start with only a small rotation in each size. Add more after you know which size and garment types are being used most.
When should I buy the next size?
Add the next size when the current clothing is approaching its fit limit or when you find a clear gap. There is no need to build every later size before birth.
