Comes up small

Go a size up. Specially if you have a chunky baby like me


It did its job but I found that because of the happy nappy over the top, my baby had red marks from the poppers after.


Good fit and able to last. Easy to use

Paloma Santos
Worth buying it

I bought size Large for my 17 months old daughter and it fits perfectly. She will probably use it for another 6 months
