When and how did the dominance become obvious?
With my older two, they were unmistakeably righties from the time they started being able to bat at toys hanging over them and grab things. DS2 confuses me, though. He's almost 4 and he doesn't really have a dominant hand. When he was about 18 months old, I noticed that he was doing a lot lefty - switching sppons to his left hand if I put it in his right hand, offering left foot first when putting on shoes, kicking with his left foot, reaching out for something with his left hand even if it was closer to his right, etc. I though for sure he'd be a lefty (dh is a lefty, so there's a genetic link), but it's never really resolved to left dominance. I'd say he's moved away from the left dominance toward 50/50 and sometimes seems to use his right side more. He's not very into coloring or drawing, though, so it's difficult to tell. When he does things like that, it's usually because DD has coerced him to sit and color with her, and I think he watches to see what she does and copies her - but he also sort of scribbles disinterestedly, switches the crayon from hand to hand, or even holds a crayon in each hand and switches off. I'm just wondering if he might be a lefty trying to find his way in a righty world or what?
