My 5-mth old bb also has the same problem.I have tried a lot of cream except hydrocortisol. I didn’t want to give him hydrocortisol as i learnt from newspaper that it'll bring bad effects for prolonged use.
recently, my bb's rash has become so severe that I really have to try. The cream really works. When it is applied in the morning, the rash disappears in the afternoon. I plan to use the cream twice a day for my bb and only for the areas with rash. I'll stop using it when the rash is gone. I still worry about any bad effect of the cream.
