my baby is 10 months old. she kept getting this rash evry other month when she was 2-5 month old. i change her diapers frequently, and apply this Johnson and johnson nappy rash cream after cleaning her each time i change her diaper. so after that she is not geting th rash from past four months. i also changed her nappy from pampers to huggies. you can try and change the brand of the nappy also.
