Both my girls had it and at first I was told it was hormonal and it would clear, with Jovie's it never seemed to clear and we found out later that it was due to her milk allergy and because I was having milk. I think the best thing is to use your breastmilk on the skin as there are special properties to protect the skin. For moisture plain sorbolene cream is best, because even the Johnson's products have additives and preservatives that your baby might be reacting too. My good friends children reacted to parabens and sodium laurel sulphate used in most lotions and moisturisors. She only found out by trial and error.

So while its completely normal for them to get hormonal rashes as your body changes post baby, its also something to be wary of and keep your eyes on. If you try natural products without additives, you may find they are super sensitive this early on, and this too should settle as your baby gets bigger.

Goodluck!
