My 6 week old baby had developed some tiny pimples (tiny bumps) on his face for the past 2 weeks, they become very red right after his bath. At first I thought it was caused my application of moisturiser (Mustela) and the hot weather. But since then I had stopped applying moisturiser and switched on the air conditioning whenever the weather gets warm. As I feed my baby with both breastmilk and formula (I have a very pitiful supply of breastmilk... but never mind.. that is another story), I was told that it could be my breastmilk or the formula (Morinaga)that is too 'heaty'. Will be greatful if you can share your experience.
