Who took my baby?

And could you please return him because I miss having a small baby. This big guy is weighing in at 15 1/2 lbs. and is currently wearing 9 month clothing. I think he was in his 6 month clothes for like a week. Well, besides growing like the weeds in our front yard he is just so fun and has started to do a real laugh. I've tried to capture it on video but he seems to know and won't do it as soon as I turn it on. Sneaky boy...
