Signs Your Baby Needs a Bigger Diaper Size

Babies grow fast, and diaper sizing doesn't always keep up on its own — you have to watch for the signs. Here's what to look out for.

5 signs it's time to size up

  • Red marks or lines around the waist, thighs, or tummy after you remove the diaper
  • More frequent leaks, especially at the sides or back
  • The diaper feels tight or hard to fasten without stretching
  • Visible gaps have vanished — the diaper looks stretched instead of relaxed
  • Your baby seems uncomfortable or fussier during diaper changes than usual

Weight isn't the only factor

Two babies at the same weight can need different sizes depending on body shape. If you're between sizes, sizing up usually gives a more comfortable, leak-resistant fit than sizing down.
