The beauty of the One Size nappy system is the flexibility of it. Not only does it take your baby from birth to potty, but you can also pop in the booster liner as your child gets older, to add extra absorbency. I don't find this adds much bulk to the nappy at all. We supply our Popolini One Size nappies with a booster liner included, however we also sell them separately as we know that some customers may have purchased their One Size nappies without the pop in booster liner when their babies were small, and now require them as baby is growing. I find it handy to have some extra liners available as if baby has done a poo, but not wetted the nappy, it seems silly to have to change the entire nappy just because the booster liner is dirty. If the nappy itself is clean and dry, you can simply add a new pop in liner!

Available singly or in twin packs.
