5 Month Old with Milia

ashleyip92

My Little one will be turning 6 months in a couple weeks , she was born with a milia on her bottom lip and it's still there. It looks a little deep under the skin. Her pediatrician said it "should" go away. But I googled around and no article gave me some assurance that it's normal for a 5 month old to still have milia on their skin. Has anyone have this issue too?
