My DS would try and bare his own weight from the day he was born, he'd like nothing better than to be held upright and try to push himself upwards with his legs. DD is 5 and a half months and won't try to bare her own weight at all, she kicks and wiggles her legs like there's no tomorrow and rolls over, even manages to turn a full 360 circle in her cot but won't even attempt anything of the sort. Is she being lazy or it something I should be concerned about??!! I hate comparing what she does to when he did things usually but this is something that just keeps popping into the back of my mind?!
TIA
PS she is much heavier than he was at this age so I don't know if that would have anything to do with it?
