Take pictures of him and blog about it. Duh.
I talked about in this post how we have been dealing with the 30 minute intruder. Jack sometimes makes up for his short naps during the day with 1 long nap. During the first hour of this long nap I am very productive and grateful to get things done. The second hour I start to get lazy and catch up on blogs, facebook, etc. By the third hour, I start talking on the phone really loud, putting clothes away in his room, accidentally slamming the door, etc.
At two hours and 50 minutes into his long nap today he started to stir and I thought this is it, I can finally play with my boy, so I ran upstairs, threw open his door along with the blinds, and yelled, "Baby Jack! I've been waiting for you to wake up for SO long!!!" (Yes-I call him 'baby Jack' 90% of the time.)
He grunted a few times, shot his legs in the air, and then they slowly lowered back down to the crib while his head fell to the side and he passed back out.
