molding helmet question...

Ch

My 6month old (tomorrow) had her first 23 hours in her helmet today. She was extremely fussy tonight so I removed her helmet to give her a bath and wash the helmet and she has a bumpy red rash on her forehead. apparently it is super itchy too because in a matter of seconds she'd scratched herself until she was bleeding. I've put mitts on her and given her a bath and brushed her hair/head. is there anything else I can do to help?
