My baby had a skin tag on her armpit when she was about 7 months then one grew in the back of her head, which looks like a mole, now there’s more growing around then, and her hair falls out when she bathed, just a little bit not a lot and she has a little bald spot by the mole In The back of her head, she doesn’t pull her hair or bug it, should I get her checked, last time they just said to wait and see if her skin tag on the armpit would fet any bigger it has a little… btw she is now 17 months old.
