I using Alobaby Milky Lotion for my baby face as she got sensitive skin. You can try is organic based. Yours look serious if I think see PD better at least see whether got some medication for faster recovery.
suggest to visit PD, last time my boy developed on his cheeks. no joke. skin peeling.
I think it’s best to see pd for it as newborn skin are delicate & sensitive
try aloe vera gel to soothe the redness...dont apply heaty lotion..
Better go see doctor before applying the right one.
Oh dear mummy! Suggest to go PD
you can apply physiogel AI
