Big hugs for you and your DD. This is not a cry over nappies, it's about a poor little bottom that must be hurting and I think everyone can understand how upset you must be feeling when you're going to incredible lengths to do the best you can to solve the problem. I haven't got any advice on the bad batch of nappies but I hope you are able to sort something out. How old is your DD? I think I'd be asking for a referral to take DD to a paediatrician or skin specialist about her poor little bottom. I feel so sad for you both.
