Hi my 7 month old just broke out in this dry rash around her mouth and cheeks, no where else on the body, she is breastfed and I did have some milkshake yesterday so I was thinking it could have something to do with it. Was just looking to see if anyone else experienced the same. I hope itโ€™s just because of her teething. Thank you in advance
