My boys head was 39cm circumference at his 6 weeks check and hasn't been measured since, he's grown into it though. As for me when I was a baby I was in the 90th centile of head sizes at that age and I'm doing fine so it really doesn't mean much xx
My boys head circumference was around 50 and his height 59 🩵
I don’t remember what my boys sizes were off the top of my head but my HV told me his head was on the bigger side compared to his length and weight being in proportion
My health visitor never checked my LOs head circumference.
