She has a pretty gruelling book and speaking schedule which takes her away from the children for days at a time.
She made it seem that whenever she is home she cares for the children entirely by himself, with just a little help from Mady and Cara but Jon has outside "helpers".
Her tour schedule was hectic for the past couple of months, if Jon was at home with the children all that time and wanted to take a day off from buying party decorations and not participate in her photo op, then good for him.
Don't refer to the photogrpahers as "papparzzi", then tell your child not to use the word five seconds later.
It's quite clear that she has very few friends. Even Carla, who she has known for years was at the party to help and was probably paid for her time, just as she used to pay her to babysit.
I don't know what happened between Kate and Beth Carson, but Beth was barely in season four and I would have expected someone that Kate referred to as her closest friend to have been at the party, if only because Mady and Cara were such good friends with Beth's daughter Taliah. Taliah's apparently been replaced by some kid who looks like that heinous little cow John Stamos got stuck with on ER after her useless mother died.
