I bought numerous times pampers for all my kids.and oldest child is 8 years old always had a problem, never took note but now recently my 3 year old has a rash all over where the nappie stretchers ,took him to Dr and he does not have a skin problem,was just that packet of s nappies that you buy at your local shops,and to top it up I bought again packet of pampers nappies and the stretch part to tie the nappie just broke off and I buy a big size for more play on his body.I'm really upset and dispointed as I been a fan of pampers for years numerous problems and this was the limit the nappie is torn,don't stick,andd if you pull to tie it ,it breaks off. Hope I can get some positive feedb back.as I'm putting this on social media!!!
