Double their height on their second birthday?

[BroccoliSpears]

I've always believed that you measure a child on their second birthday and double it to predict how tall they will be as an adult.

Anyone else heard this one?

Or you could share any similar ones.

(Dd is 2 today and is 2' 10 1/2", so 5'9" as an adult?)

my MIL believes this so I measured ds on his 2nd birthday. Although he is the tallest 2 year old we know and is on the 75th centile thing for height and weight it worked out that he would be 5 ft 6! I suspect it's an old wives tale.

You can never really predict. How many families do you know with same parents but different heights of children. My dad was 5ft 8 and my mum 5ft 1.

My sis is 5ft 6 but I'm only 5ft 2.

Her DH is 5ft 10 and so is her DD!!

My DD is 5ft 3 but her dad is 5ft 11!!

Checked dd as well now. She was 91cm at 2 so this will make her 182cm or just under 6 ft. If she follows the centile shes on she will be 173cm. That's quite a difference

Well, I'm throwing grandparental genetics into the mix for ds. FIL was 6'3", taller than dh. My theory is severe childhood asthma stunted dh's growth (dh's mum was 5'6" which was quite tall for her generation, although she's shrunk a bit in old age) so as ds is fortunately asthma-free he should be taller than his dad.
