Ladies,
I know it's tough, but just think--you'll be out and about again in the blink of an eye, really. I too am housebound with a 4mo and a toddler, and we pass the time by trying to think of fun things to do here--garden, put together a great soup, shop on-line, etc. Decorate your homes to get yourself in the Christmas spirit--have DH buy some ribbon and garland, and go to work!
Also, I really suggest listening to some uplifting music and burning wonderful smelling candles around the house. It makes a difference mentally! Don't forget a nice bath with bubbles, and fabulous books--again, bought on-line.
These practical things have gotten me through this once before, and now again. Hope they help...
