Hello! I just put my LO on a new formula about 2 1/2 weeks ago. She was on enfamil A.R and I had to switch her to Similac for spit up (equivalent) because WIC only covers similac. She just started getting this rash on her face about a week ago, she usually gets it right after she eats... Anyone have any idea? My friend told me that the rash on her face looks like the teething rash they can get but she is only 2 1/2 months old. She drools a lot but I don't think she could be teething this early! Any ideas??
