My daughter is not even three weeks old and this rash/irritation came out of no where 😁 called her doctor and they didn't seem to concerned dismissing it for baby acne, said to come in only if it gets worst. She has not been in the sun and nothing besides aveno baby wash has touched her skin. I've been putting my breast milk on it as they said it could help. Any other mothers experience this?! Breaks my heart but she is not in any discomfort.
