Wing droop!

We are getting terrible wing droop on all of Dottie's nappies, even the ones which claim the snaps are positioned in a way to prevent wing droop.
Is it goodbye to all her front fastening nappies? I hope not 'cos it's a struggle to get a good fit and she always gets red marks on her chunky thighs with side snaps, no matter how loose I fasten them!

I've never had great success with any front fastening nappies. M has really chunky thighs and side snaps always give a much better fit. We don't generally have issues with red marks when using them either.

Are they sized ones? Or one fits all? I have tuttos and I adjust the rise to give extra just in the middle by one popper iyswim. Problem solved ;-)
