Hey mama, You could start with some calamine lotion and keep the area clean and dry. I’d suggest bringing baby to the PD just to see what’s up - baby skin is sensitive so good to treat it. Also, could it be the folds of the skin where the dirt is gathering? It can be tough to clean that area so that could be one of the causes too.
It’s important to keep the area clean and dry especially after milk and bath. Apply some powder to help keep the area dry. If it doesn’t improve, you may want to consult a doctor.
