They are a cute family. But I picked up on a "strained" vibe between the parents. It could be that they are stressed, tired and mentally drained everyday. They are always saying these passive-aggressive things to each other. I hope things calm down just a little bit when they all reach grade-school age.
I've watched it several times. They really have their hands full. One of the shows though that was weird is when the 2 year olds were "pooping in the potty" the first time and Kate took pictures of them with it. Strange.
