Animal Sounds and Signs

We have been trying to teach Landon sign language. He has kind of invented his own language with it :) He does the signs close to what they are supposed to be but only actually does a few of them right. I'll interpret below :)

He has a puzzle that makes the animal noise you when put the puzzle piece in it's place on the puzzle. This is what he is playing with. The first sign and sound is a cat, you sign it by showing whiskers on your cheeks. Next is a dog. He does this one right too, you pat your leg like your calling for a dog. The next piece was a cow, but he doesn't do a very good "moo" for me. When I tell him to do the rooster and he is grabbing at his chin he had picked up the pig piece and is trying to pig, the real sign is your hand under your chin. Then he finally does the "doodle doo" for rooster and is grabbing at his head, the sign for that is 3 fingers on your forehead. So he is close :) I just think he is adorable trying to do his signs and sounds :)
