The other day I was on the phone with my mom and Cooper was watching "Baby Einstein - Neighborhood Animals" he loves watching it lately because he is so obsessed with animals. Well anyway, there's a part on the dvd where there are kids singing "Old Macdonald" and when Cooper was watching it he kept yelling something over and over, it took me a minute to realize that he was singing "ee-ei-ee-ei-oh." It was so cute! He kept yelling it over and over at the top of his lungs, you could tell that he was really proud of himself too. Yesterday I tried for like half an hour to get it on video but he just wouldn't cooperate, this is the best video that I got, I don't know if you can tell but he does say it once (minus the "oh") and then to tease me he mouths it to himself silently.
