That's how mine were. DD was bald for a LONG time. She grew some peach fuzz around six months, but didn't get any real hair until she was over a year old and it grew very slowly. DS had a full head of pitch black hair though. The nurses kept coming in to see him because none of them believed he had so much hair as a newborn. With DD I was eating tums for 9 months and with DS I didn't have heartburn. Go figure.
