My 4 week old started getting what I thought was a little bit of baby acne about a week ago but the past couple of days I have noticed it gets worse and more red normally after a feed. Once she has had a feed it flares up but then calms down quite quickly so I’m not sure but I am now thinking could this be CMPA? She has been more fussy than normal the past couple of days and seems to be in a bit of discomfort maybe a little constipated but generally is a happy bub. I attach some pictures just wondered if anyone could let me know what they think, acne or cmpa rash?
First two pics are once flared up and the others are her skin normally.
