Libby and I have started playing a game after her naps where she throws all of her stuffed animals and babies out of her crib and then I throw them back. She especially loves when I hit her on the head with the soft ones. (I haven't ever hit her with a hard one, but something tells me she wouldn't like that as much.)
The first time I did it, I counted the animals as I threw them back in, and Libby has picked this right up.
Anytime she counts, she starts at eight and goes to nine. Then repeats. Also, sometimes "eight" sounds like "ice."
