She might be in the awkward stage where she’s sizing out of her nappies but isn’t 100% ready to be in a larger size either. When my son started growing out of size 1 nappies he’d have several daily blowouts in both size 1 and size 2 nappies. Eventually as he grew into size 2 a little more the blowouts stopped. Could that be why?
Had the same problem. Tried every brand but read cloth nappies help. The only thing that kept it in was a cloth nappy because the elastic has no gaps at all, especially up the back so it’s impossible to leak. I use miosolo x
And yes we use the premium protection ones it doesn’t stop it!
