Hi. DS is my first DC so far, is nearly 16 mos and is still perfectly happy to do his weird sideways bum-shuffle rather than walking (this doesn't bother me btw, other than it'd be handy not to have to carry him and the shopping from car to house). My friend's DD was born the same week and has been walking since she was 13 mos.
Whenever anyone asks if he's walking yet and I say no, they sigh, nod sagely, raise their eyes to heaven and say "ah, that's boys for you..." So, those of you who've got DCs of both sexes, is it true? Are girls just quicker than boys at walking and other stuff? And why?
