First off, happy birthday and Mnohaya Lita to Bobbi!
One benefit of Henry's arrival is that it has resulted in the reappearance of several of my long-lost toys. For example, I used the activity gym all the time when I was a baby, and just because I supposedly outgrew it doesn't mean it's not still fun to play with!
The one-time-use formula bottles make good playthings as well. It's not just my old toys either; I find a way to play with most of the new toys, books and stuffed animals that people have bought for Henry too. I don't know why I never realized earlier: two kids = double the toys!
