Chewing nails and slouching

Yesterday when I was playing with Ethan I noticed something new. I was chewing on my nails, a bad habit I've always had, and I looked over at Ethan and he was copying me. He had this funny look on his face, and he was watching me very intently as he put his little finger nail up to his teeth and started to try and chew on it like mommy. I was like...dang it! So now I've realized he's really started to notice the things i'm doing, so i'll have to be more careful. Today I was sitting on the couch watching a show, and he came over and climbed up beside me, and seriously, he slouched down in the couch just the way I was sitting. They grow up too quickly. Now I'm going to have to try to be more aware of everything that i'm doing.
