This is a new one and I cant figure out how to fix it or if its just a shape changing issue. A couple of my night nappies have basically started sliding down during the night so that in the morning they resemble the way some young boys wear their jeans these days (with the backside hanging out!)
Ive changed the way I fasten them (poppers) fiddled with them and even taken out some of the absorbency to see if it helps. What puzzles me is that he is not a mover! We co-sleep so I know how much he is moving at night and he barely moves at all so it seems even slight movement is meaning the nappy is slipping down.
He is long and lean, hes like a bean pole
however Im not having the same problem with all my night nappies and they have only recently started doing it....same nappies Ive been using for at least 4 months or so!
