Okay my daughter is two yrs old, she was perfect when she was born but had a huge head, when she was about 6months old she started getting this light brown, raised, splotchy, bumpy thing on her side, when i took her to the derm. he said it was a linear mole. Well now it is spreading across her hip (gotten larger) and now there is a tiny spot under her belly button. what do u think it is? ive looked it up nd it looks like nevus . is it?
