Hi there. Thank you for posting your question with Healthcaremagic. I will do my best to help you.
I'm inclined to go along with your pediatrician
, at least to the extent of implying that whatever these scabs are they are hardly serious and almost certainly your baby will out-live them.
They could be a mild dermatitis
. If they effect the side that she tends to lie on then one would wonder if there might be something in her pillow or detergent used to wash it to which she in sensitive. A bit of detective work may be called for.
A very mild steroid
cream like Hydrocortisone
0.5% would almost certainly clear them off if you continue to worry.
I hope that I have answered your questions fully and been of some help. If you have anymore questions please contact me again anytime.
Dr Andrew Rynne.
