I really don't understand the annoyance
So many posters are mad that the show is all about the kids now. Of course it is - they have kids now! That's life.
The show started out about their life together as a little couple. Well they're parents now, and when you have kids, pretty much everything in your life includes the kids. Especially since the kids are also "little people," so why wouldn't they be the main part of the show (which is about little people) now just as much as Bill and Jen?
I mean, what do you expect the show to be about now? This IS their daily life now. This is their family.
