We watched the Wiggles for hours. (Lots of Dancing and loudness involved) That kept him up and moving about. We also did some baking, so he got to play with the dough and such. We did art projects and drove remote control cars through the house. (Bumber cars...he was a destructive little tyke!! *lol*)
Basically, anything and everything that we could think of to keep him upright and moving. Just like your Izabelle, the second he was sendentairy for more than a minute, he would doze off, so it became our sole goal to not have him sit down. If she likes to dance, put on some great music and dance as much as possible, or excersise videos...anyth ing like that.
My Mom and I worked together. I was divorced and living by myself, so she came over for the evening to help. I hope your husband is able to get the time off to be there with you. It's much easier when there's at least two people to keep the energy level up.
