As for the grandparents, his dad has passed and Kate has said many times the grandparents are not involved with their daily lives. She does also say they do live close by. She never has gone any further with why they aren't involved.
Also, someone mentioned laundry. Her neighbor goes to the house every Thursday to fold all their laundry! That woman is a saint!!LOL
I noticed the comment about them putting the presents out for the kids and they never mentioned Santa at all. I was so glad DD wasn't watching with me and I remember thinking that when I was watching it! I watch this with my DS(4) and he loves it! He gets a kick out of watching all the kids.
