My baby actually had a rash similar to this and i tried every remedy for it for days and the only thing that worked and kept the rash away was aquaphor 3in1 diaper rash cream.
Aquaphor works wonders!
I do have the aquaphore healing ointment idk if that’s the same thing?
I’ve heart tubby todd all over is amazing for anything.
@Brittany idk if that one would work if he still has the rash after using it but i make sure i also put a thick layer on it every time i change my baby
Maybe a heat rash? Try keeping it cool with a cool wet rag and try hydrocortisone cream. Hope ur little guy gets better ❤️
