Heat rash? Cows milk allergy? Irritant?

🍁 𝗻𝗶𝗰𝗼𝗹𝗲.

Little one is a little over 5 weeks and this rash started yesterday but subsided this morning only to come back again. She’s been fussy like crazy and would put up a fight taking a bottle.

I’m taking her to her pediatrician first thing tomorrow but I was wondering if this looked familiar to anyone? The symptoms? Anything helps.
