re : YY
I guess she wants to define her situation in your family, eg, 1st one you'll feel important. Maybe she feels unstable/unsecure... how about at this stage, try to ask her opinion first, eg. YY, how about we give this toy to YL? do you feel it's ok? I'm sure she'll answer you : OK law.. as she is not really want to play YL's toy (over age ma), but really want you to pay attention on her!
re : Yoga Championship
