question: baby's head is too big. Thanks a lot!

Sorry I can't type chinese at work.

My daughter just had her 6 months old check up today. Everything is fine except her head is too big (off the chart). Her head size was 50% when she was born, but suddenly jumped to 95% when she was 4 months old. Pediatrition asked me to pay attention to that during her 4 months old check up. This time the head size is 100%.

My hu*****and does have big head. So pediatrition said that my daughter may got that from my hu*****and.

But pediatrition suggested me to take her to the specialist (neurologist) to have a further check. They may give her a CAT scan on her head to see more details.

Any mom have this kind of experience? Thanks a lot!
