What age are size 6 nappies for?
Size 6 nappies are designed for little ones weighing 14kg+ (31lbs+), which is usually from around 3 years old onwards. Every child is different, so while some toddlers may need size 6 nappies a little earlier, others might need to wear them for longer.
For parents looking for the best eco nappies for their little one, Kit & Kin size 6 nappies are a fantastic choice. Made from plant-based materials, they’re gentle on delicate skin and offer up to 12 hours of leak protection, making them perfect for keeping your busy little wriggler comfy - day and night!

When to switch to size 6 nappies?
If your child’s current nappies are feeling snug or you’re noticing more leaks, it could be time to move up to size 6 nappy. A nappy that’s too small may leave red marks around the thighs, sit low on their back, or become tricky to fasten across their waist.
Switching to Kit & Kin size 6 nappies can help keep your little one comfortable, whilst making sure they stay dryer for longer. Our award-winning eco nappies are made with biodegradable plant-based materials and are hypoallergenic, making them one of the best eco-friendly nappy options for growing toddlers.
