Buying baby clothes is a lot like playing the lottery; you hedge your bets on a number, and hope it’s the right one.

But it doesn’t have to be that way. While it’s true that babies grow really fast, it is possible to buy clothes for them that will fit - at least for now. Use our size and age chart to help determine what size you should buy.

Remember: when in doubt, make your purchase based on weight and height rather than age! It’s always safe to go one size bigger, except in the case of baby sleepwear.
