My LO is 16 weeks and sleeps through from 9pm to 5am but her nappy is leaking every night. I have tried 2 nappies, nappy boosters , one nappy on the right one and one over the top back to front. Has anyone got any suggestions on what I can do to prevent her leaking? It doesn’t seem to be bothering as she is sleeping well but it is an awful lot of washing!
