What age are size 3 diapers for?

Our Kit & Kin size 3 diapers are designed for babies weighing between 6-10kg, or 13-22lbs, which is typically from around 3 to 6 months old. Of course, every baby is different - some little ones may need size 3 diapers a bit earlier, while others might stay in them for longer.

If you're looking for a gentle, planet-conscious option, our hypoallergenic diapers are made with plant-based materials and are specially designed to be kinder to sensitive skin. They're also dermatologist approved, giving you total peace of mind that they won’t irritate your baby’s delicate skin.

How to tell if your baby's diaper is too small

If your baby’s diaper is starting to feel a bit snug, it might be time to size up. Signs to look out for include red marks around the waist or thighs, frequent leaks, or difficulty fastening the diaper comfortably.

If any of these signs sound familiar, it might be worth trying the next size up, to keep your little one comfy and dry. Our hypoallergenic diapers are designed to give a secure fit with plenty of wriggle room, all whilst keeping your baby dry and comfy for up to 12 hours.
