Ok, I am a first time mum so need to ask a question as I don't know much (but with everyones help I will learn )

Lil has had perfect baby skin on her face since she was born....until Monday just gone. I noticed a few pimples under her eyes but didn't think too much of it until Tuesday. Her face looks like she has broken out in acne or something. Little red pimples all over her face.

I have done a few searches on the internet and have come up with ..milk rash or milk pimples? I am breastfeeding.

However I am still not sure and am hoping someone can help. Is it normal for babies to break out like this? Has all of your children gotten this as well? Is there anything to make it go away? Heat seems to bring it out more from what I have noticed.... she doesn't seem to be in distress from it.

Thank you in advance
