It seems the most likely cause of her large head is...me.
Dr pulled out a tape measure & measured my head & said 'uh-huh. thought so'
My head circ is 60cm ... apparently that's big
Same thing happened to us. But they only had to look at DH to say 'Hmmm. I think it's pretty obvious what's going on here. No offence mate'

I'm glad all is well

We had our latest check up last week and DS2 is still just over the top of the chart but following a nice growth pattern
