Please can someone advise, my dd2 is 14 weeks and almost daily leaks out her nappy when doing a poo. The nappy itself is never full but she seems to explode at the top all over her back. I have tried Pampers, Kit & Kin, Waitrose own brand, and am currently trialliang sainsburys. I've tried sizes 3 & 4 - she isn't a fat baby but she has quite large thighs. Can anyone recommend any other nappies...?? Thank you!
