my poor baby girl is teething so she has diarrhea awful and I keep her clean so so clean and she has a very bad case of diaper rash and I feel so bad for her because she screams every time I have to change her. she has never had diaper rash before. she got chemical burns from huggies snug and dry diapers but we stopped using those immediately and its been months and now she's got diaper rash and I just feel so bad for her :(
