Seriously what is going on
they are the correct size (stage 4 and he is 17lb), I spend ages making sure it is properly on, adjust leg bits, make sure it isn't folded over on the back etc. But pretty much every time he wakes up of a morning or after a long nap he has wet through it on to his clothes at the side and back and the nappy doesn't even feel full. 5 pissing grobags I have gone through in 4 days.
Am I missing something here? Never had this problem with DD!
