Whats the average babies head size at birth?

**~breeze~** · August 3rd, 2008, 02:01 PM

Hi, just wondering what the average size would be for a babies head circumference (sp?) at birth?

What was your babies head size?

DD was 37cm, just wondering if thats an average size or big.

Sorry mods if this is in the wrong area, please move if you need to.

Thanks

I think the 'average' is 35 cm???????? So 37cm is not abnormal, but not small either

My DS was 34cm when he was born at 35 weeks! And he weighed 5lbs1oz. So a good sized head for his gestation LOL. Poor child was waaaaay out of proportion for along time, my DH says he still is

ETA and what I find hilarious is that my step-sisters first baby was almost 10lbs, but his head was 33cm. People love to say how easy I must have had it getting my DS out because he was so tiny/light..........um, no. It just goes to show, it's the head size that can make a difference, not the weight!

According to the blue book charts, the 50th centile is 35cm for boys and 34.5 for girls, most of the ones I hear about on here and IRL are between 33 and 36cm.

Mine were 34.8, 34, 34 and 37.

Josh's HC was 34cm and he was born early at 36+6.

DD's HC was 35cm, but length was 55cm and weight 3.6kg. (Don't know pounds/ounces).

I asked my SIL this questions the other day - not out of a book answer - she is a midwife and has been for 10 years. She reckons the average is 50cms long and 35cms head in her experience.

Mine
DS 36, 4.125kg 56cms 39w
DD 35, 3.570kg, 51cms, 40w+1

DD1 - 41+1 - HC 34.3, L 50cm, wt 3320 / 7lb 5oz
DD2 - 41 - HC 34.5, L 50cm, wt 3885 / 8lb9oz
DS - 39+5 - HC 35.5, L 52cm, wt 3840 / 8lb 7.5 oz

3.6kg is........... 7lb 14oz

or 7lb 14.98 oz to be exact

LOL! The things you learn....

I thought 35 was normal... I thought that 8lb was normal so it is almost. But I thought 55cm was normal. Both my girls were 56cm long, 4kg and 36 head cm.
