I don't believe for a minute that Kate does all of that by herself. She had her "friend" there with Kendra the whole time. I'd better dollars to doughnuts that that is her nanny. And Kate going on and on about how she doesn't take time for herself? LMAO! Plastic surgery, trips without the kids to promote her books and she finds time to work out. She's a joke.
Kendra has a husband that treats her like a queen. She should spend more time with the little one, but pre-school is great for socializing your kid. Nothing wrong with that and giving him a leg up in his academics. He is four, after all.
