The fascinating discoveries of a 2 year old

Wow I am truly impressed with how quickly Eric has been picking up his vocabulary!!!! He's tried to say Okie Dokie Artichokie. He's been enjoying his Leap Frog videos. He does a lot of mimicking so I really really have to watch what I'm saying. LOL he's figured out ice cream, pancake, show, pants, shirt, yucky, stinky, LOL and outside, and oh shit almost sound the same. He's totally fascinated by the movie Finding Nemo!!!! We are on our second run with the movie and of course he pronounces fish like shish and turtle comes out turl, bath tub is ba__ tub. He loves to 'talk' on the phone. He's got a dummy cell phone and an old cordless hand set that he plays with. Of course his absolute favorite is being outside in the yard playing in the dirt. Oh and he loves 'stachios'. I've noticed that every once in a while Eric will have these sudden jerky movements like he's possibly having a mild seizure or possiblly has turrets. I haven't noticed his eyes rolling but I'm a bit concerned and I probablly need to set Eric up for his two year check. I've been kind of lazy about things because he seems generally healthy. He runs around and plays and shows all emotions he can also identify things such as pictures of objects.
