What age are size 2 nappies for?
Our size 2 nappies are designed for babies weighing between 4-8kg (9-18lbs) - typically from around 6 weeks to 4 months old. However, every baby grows at their own pace, so some may need size 2 nappies a little sooner, or might even stay in them for longer.
If you're looking for a gentle, eco-friendly nappy option, Kit & Kin size 2 nappies are a fantastic choice. They’re super-soft, hypoallergenic and made with plant-based materials, with patented technology designed to keep your little one dry.

When to start using size 2 nappies?
You'll know it's time to switch to size 2 nappies when your baby starts approaching the upper end of the size 1 weight range - this is usually around 5kg (11lbs). Look out for tell-tale signs of a growth-spurt, like frequent leaks, or the nappy feeling snug around your baby’s tummy or thighs. If you’re unsure about sizing up, here are 5 signs your baby’s nappy is too small.
If you’re looking for environmentally friendly nappies for your baby, our Kit & Kin biodegradable nappies are sustainably made from super-soft plant-based materials that won’t irritate delicate skin. So, whether you're searching for the best eco nappies for your newborn, or moving up to size 2 already, Kit & Kin hypoallergenic nappies are designed to protect delicate skin - as well as be planet-conscious.
