Our first slept most of the time in utero and continued to after birth, she has always been calm and quiet when compared to others
however..... number 2 was constantly kicking me and doing somersaults etc inside and she is much much much more active than her sister and has no fear of anything now that she's out. (not to mention she sleeps about 1/2 as much as her older sister did at the same age) As far as intelligence goes - she certainly seems to be close to where her sister was at this age, but since she's only 2 we have nothing else to compare her to.
