SAHM's, how do you entertain your baby all day long?

Sadly, I don't get out much due to my dog's separation anxiety issues. I take him with me when I can, but he's big so it's a lot to handle him and a baby, plus it's going to get too cold to eat at outside restaurants soon so we're going to be stuck at home even more.

Things get pretty boring around here. We play- I put her in her activity gym, I read to her, we listen to music, sing, play with her toys/rattles. She seems happy, she smiles a lot. I'll also put her in her bouncer when I need to get things done, and I'll sing to her as she watches me do things around the house. We'll also sit out front, we have the front yard fenced in for the dog, and she loves the fresh air.

I guess I just feel bad b/c it's pretty redundant. What does everyone else do with their babies all day long?
