Just more indications that Kate is clueless on what the kids like to do. Or maybe, she just ignores what the kids like to do, and FORCES them to do what she wants. Kate doesn't listen. That's pretty obvious.
Interesting isn't it? Every pictures you see of the kids smiling are almost always when they are with Jon. Photos of the kids looking said, tired and popped out, are always when they're with Kate.
