some differences i've noticed

isaiah is more social - he gets incredibly excited when you look at him. isaiah is also more emotive than ellen - he laughs more than i remember she did, but he also gets upset more easily. ellen is a heavier sleeper than isaiah - i'm hesistant to even enter a room he's sleeping in. ellen slept through everything. i could pick her up and move her change her diaper and she wouldn't wake up. isaiah has a favorite toy already - ellen didn't really attach to anything until she was about one. and then it was only for a little while. i was like that as a kid...i had favorite stuffed animals for about a month, and then i picked a new one to be the favorite.
