Nervous about giving daughter Propranolol

[smilo143]

I have a 5 month old daughter with an H on cheek about the size of a nickel. I have a 4 year old that had an H on her crown of head when she was baby and it faded completely way by 3 years old(hair also covered it up). I went to Vanderbilt childrens dermatologist(Mike Smith) this week and he is a believer in Propanolol. He has seen great results. But I am very nervous b/c drug has not been used very long on babies and is still a trial drug. Has anyone heard of a face H going away of this size and leaving no scars? Anyone had bad side effects of Propanalol(i've heard BP/glucose needs to be monitored)?
