DS and DD are so different. I know all siblings differ from each other but it is so extreme! It started with being born, one two weeks early, one two weeks late. Then DD was wide awake, DS always slept. DS on the move at 6 months, never really mastered sitting up though, was too busy crawling. DD been sitting really well since about 5 months, and doesn't even roll. DD babbles, DS never did. I could go on but I won't. Anyone else the same an if your DC were this different how do they get on with their sibling as they get a little older?
