My baby has so little hair on his head. I see other babies with a head full of thick hair but it has been 6 months and my baby is still almost bald. Will she ever grow her hair?

My daughter, now 3 year old used to be a botak until she's 1.5yrs. We had initial worries, but glad we did not succumb to old wives tales (rubbing XO onto the scalp, etc) Now 3, she has such a long mane of hair she refuses to cut. Cos' she wants to be a princess... ;) My twin girls are 8 months and all they have is a tuft of hair in the centre - affectionately termed the mohawk look. Probably the only times they will sport a Mohawk! That said, it just takes time. Not every child is the same :)
