I'm curious. DS1 did everything early- physical milestones/ speech/ cognitive etc as a baby and toddler. He is now 4.5 and bright and curious (I think) but doesn't stand out particularly amongst his peers in terms of intelligence. DS2 is now 18 months and has done pretty much everything late (at the very late end of normal- doctor says he is not actually delayed.) In your experience does this say anything about their relative intelligence? Will it predict what they will be like in the future according to what you ahve seen from your kids? They are both amazing and lovely in different ways and it doesn't matter at all how 'clever' they turn out to be , but I am interested as they are so differerent and wonder if this means anything or nothing. Thanks!
