this thing about your child being half their adult height at age 2 - is it accurate / true?

[BocciBalls]

Just wondering... DH very tall, (6'4") I'm short (5'3") so DS (now 22mo) should be average of the two plus a bit, so about 5'10" - 6'.

I have heard / read that you can estimate adult height as at age 2 a child will be half their adult height ... but on ds's current height I reckon he's headed for around 5'6" unless he grows by 3" in the next few weeks.

Does anyone know if this is an accurate indicator - and if so does it mean on 2nd birthday or eg at 2.5?

Not bothered particularly, just curious as everyone goes on about how he must be going to be tall like his dad ...

I am taller than both my mother and my father. How did that happen then?

I'm taller than my Dad and shorter than my Mum. And my Dad was the milkman.

What's wrong with my family?

The word unique springs to mind SOH, especially when I think of the things your bil can do.

I'm not sure all the theories work tbh...i did the girl predicted height thingy in the red book for my DD..it said 5'8...thought that might be right as DP is 6'3 and i am 5'6 but she is 16 now and only 5'5...so that was wrong unless she has more growing to do. She was very tall for her age (and compared to her friends) until year 9 and then she stopped growing.
