Some babies stay bald until theyre 2. Its normal. My neighbor has 6 girls and 1 boy. 3 girls lost their hair entirely at around 4-6months and grew it back by the time they were 1.5-2 years old

My daughter didnt lose too much just around the sides but you could barely tell. Shes 10 months and her hair has gotten so long since then.

My daughter did. It all grew back.
