Dd (11 weeks) has a rash on her face and head. The pediatrician said it was just baby acne, but I'm pretty sure it's a dairy intolerance (her siblings and cousins had this problem). So, I switched her from the Similac Advance formula to Alimentum. Sure enough, the rash was much better after about two days. However, she has been spitting up so much and having diarrhea and is really cranky. It was so sad because she is aspirating the formula when she spits up, it's obviously in her nose and she is choking on it too. This also happened when I tried Good Start with her, I think it's because of the broken down proteins. So, today I switched her back to the Similac. Within a few hours, her rash is back. The spitting up has stopped and she is much happier. The rash really doesn't seem to bother her. I think it's pretty clear that this is a dairy intolerance, but she can't seem to handle the Alimentum formula. Does anyone have any ideas what my next step should be? Should I try soy? I know a lot of children with dairy problems also can't do soy.
