three yr old daughter has very itchy rash. started in september on her bottom/thighs and was told by dr that it was a reaction to new diapers. we switched back and used benadryl and hydrocortizon per drs instructions. 1 1/2 weeks later it was still there and started spreading further down legs, on belly, and lower back. we went back to her dr and she prescribed an antibiotic cream. it continued to spread so we went to the dermatologist. she said it was viral and prescribed desonide to help with itching. it started to clear up but never fully went away. its now back in full force and is all over her body again.
