My 2 yo DS was 52cm when he was born Which I think is on the tallish side.(my cousin was 54 cm and he's now 1.92 / 6 ft 5ish).
After being in the 75th percentile, he's now gone down in the 25th and people are surprised that he's 2 because he's so short. And he's not quite walking yet as he's had meningitis. But I've never heard that that has any impact on growth.
My GP said one shouldn't pay attention to height because growth spurts can happen at any time. But he's a grumpy and bored guy so I don't like to ask him questions.
Can one say pretty reliably that a baby will the a tall adult if he was a tall baby? Or is it more complicated than that?
