Diaper Sizing Tips

- Many babies are done with diapers before they ever need Extra Large.

When to Move Up Diaper SizesHooray! You’re baby is growing! Here are some more indicators that your baby is ready for a new size:
- If you start to see leaks, and you’ve tried all the troubleshooting tips.
- If you begin to see deep red marks on baby’s skin that indicate the gPants are too tight and you have no room left to expand on the adjustable waistband.
- Your own gut instinct—it’s the best tool you could have!
