Behaivior Out of Control

I feel like this past month both kids are out of control. I know they are not getting as much social interaction as they should but that will come in the new year with school. They just won't listen to Mike and I at all. Child gates do not work on either child. Carter has this new thing where he likes to open the gate to the kitchen and get into the frig or the sink or anything that looks interesting. Yes, we have already tried a frig lock! He can get it open too! They have also become SNACK hogs and it is driving me batty. All they want are snacks. Provided they are healthy I have no issue but it feels like it is one after the other. They finish a banana and want a granola bar. I CAN NOT WAIT until they get into pre-school and have a little bit of a schedule and discipline from someone other than Mike and I. They seem to take discipline better from others than they do from us. I am not sure why, maybe they have just been home too long! I thought I would never want the day of school to come but right now I am welcoming it and I can not wait! I am not sure if it will be full time or part time but either way I know Mike and I need some sort of a break from this routine. This routine is not working anymore. Our 1st appointment for Carter with the Manchester School District is 11/18, then 11/26 then 12/4! I had a nightmare lastnight about calling the VNA program to inquire about Chase. I am not sure why but it was not pleasant. The woman was extremely rude to me and treated me like my children were lepors. I know this would not happen I guess just my internal fears coming through in my dreams. Why can't I dream about a vacation on an island where Im sleeping in a hammock with the wind blowing off the ocean, doesn't that sound a lot better?
