I took Alex to his 4 month checkup yesterday. He is 16lb and 26 1/2 inches long. So he has grown 6 inches in 4 months. He's a tall baby! The pediatrician said he looked and acted more like a 6 month old baby. I'd have to agree. He thinks he is much older as well. He gets very very frustrated if Drew and Faye are playing and we're not 'playing' with them as well. He is very anxious to get moving, so he can go where he wants. I think he'll be following his big brother and sister all day. I think he'll be crawling really early so he can keep up with them. Uh oh!
