Not sure what size to choose?

We recommend choosing a nappy size based on your baby’s weight. If you’re between sizes, try the smaller size first. If you still have questions, our Customer Love team are always here to help. Send us a message with your details, and we’ll help you find the right fit.

*The recommended nappy size and quantity is a guide only.
