We are often asked what age size 4 diapers are best for. Well, this is a big milestone size. Not only will it likely be around for your baby’s big first birthday bash, but your little one will probably wear it while taking their first steps!

We obviously had to make ours extra cute. Featuring our beloved fox and tiger designs, they are the best size 4 diapers for adorable cake smash and walking snaps. Most importantly though, they’re the most sustainable diapers you can buy.

With 26 industry awards under our belt, we want to provide you with the peace of mind that you are not only doing your bit for the environment, but you’re also ensuring your baby is wearing a diaper that’s gentle and super soft to protect their sensitive skin. And what’s more, you are also permanently protecting rainforest trees in the process.
