maye you could do this:
if a mom has more then one child then maybe the oldest child, if they are under 14) that is HERS could look ater the rest of the little kids there mom has if the oldest kid fails to look after the younger the children then maybe the little kid gets a scratch or gets lost or something. then maybe a waring would come up that the kid was lost and you have to help the older kid find the little kid. lame idea but it might add a little twist to the game
