Hi, I'm just curious about this as my dd is 18 weeks, and it's been noticable that she does everything (batting at toys, then grabbing, finding her feet) first and most confidently with her left hand. Now she's started sucking her thumb and it's her left too (I'm a right hander and I definately sucked my right thumb ) - do you think I've got a little leftie or is it too early to say?
