Head circumference not matching height and weight

[mrsshears]

My 5mth old dd is between the 91st to 98th percentile for weight and height however her head circumference is on the 50th.
Would you be concerned about this? should they not match? my other 2 dd's did.I have no worries about her development but do think her head looks petite, the health visitor hasn't commented and I could well be worrying about nothing but would value your oppinions
thanks

I am 5'8 but I have a small head! Oh and I have a post graduate degree too so maybe not related to brain size....

Not a problem except embarrassingly I have to buy teenager size glasses

I say don't worry

I don't think there is much correlation; possibly for newborns, heavier babies may also have larger heads. But the head size is more likely to be genetic as time goes on. If you look around you, average sized adults have all different sized heads. If headsize is off the scales - either top or bottom end, it might indicate a problem, but as your DD's head is of absolute average size, I don't think you have anything to worry about.

Thanks thats reassuring.
The other 2 were big babies as she is but with big heads so I guess that added to my worries.

DD's the other way 'round - petite with a big head, but then again so am I! It was never flagged up as a problem. Head 91st, height & weight 25th.

I had this with dd1.

She was always on the 90s for weight and height, but had a small head.

But is is proportion to her frame. She still is tall for age but she has a small frame.
