What was your baby’s head circumference at 12 weeks?

[Babyboy2024]

My baby boy was born with a head circumference of 32.5cm. At 12 weeks it’s only grown to 37.5cm. I feel sick with worry that he’s got an underlying issue. Parents who’s babies were born with a small head circumference, did the head stay small or did it catch up to the average size for the age? What did it measure at 12 weeks?

Hi, we’re in approximately the same position with our girl, similar measurements. How has your boy developed these past months?

Not the OP, but if your baby has similar measurements, that suggests her head is following its centile, or for a girl, has gone up centile slightly (from ~2nd to ~9th), so that's very good.

The other thing would be if she's in roughly proportion – what are her weight and length like?
