Anyone else experience this? A few weeks ago DS got a wiiiiiicked diaper rash, I felt so bad for him. He had never had a rash like that before and I wasn't sure what could have caused it. The only thing different was the vitamins and we tried a apple-strawberry stage 2 fruit. So I stopped both and let the rash heal. I just started the vitamins again and again he is starting to develop a bad rash. So I'm not going to give them to him anymore. I think its the weirdest thing, but I guess you just never know what they will have a reaction too. I'm hoping the doctor can give him a different vitamin because its something he should have right?!
