I've definitely taken notice of the shorter days. My kids are noticing too and actually seem more tired just because of the early darkness. I have started exercising more in the evening as I hate getting up early and since the kids go to bed so early there really isn't anything else to do. I suppose I could talk to my wife ;)
First two days at home went well. The kids and I stayed busy both days, going to the park and running other errands. I really didn't have time to think about eating.
One great thing that happened during my last week at work was that the daycare teachers gifted me with a membership to the Betty Brinn Museum. It is an awesome children's museum and I will definitely be taking the boys there to get a few steps in. I'll park far away and walk to save a few bucks on parking and get extra walking.
Have a great weekend. The colors here in Wisconsin are breathtaking!
