Growth Spurt or the Twilight Zone?

I think I am definately in the twilight zone! Branson has slept SO much the past couple of days....in his crib...for long stretches of time! I am so proud of him. Here is how the past day went.
10:10-10:40 (short nap .5)
12:45-2:15 (longer nap 1.5)
2:45-4:15 (fell asleep on the way home from Mothers Day Out with babysitter and didnt wake up until I came to pick him up 1.5)
6:15-7:30 (slept through dinner 1.25)
9:15-6:15 (first night that he has slept entirely through without waking up and crying at least once! 9.0)
7:15-9:45 (went back to sleep shortly after waking up this morning...crazy! 2.5)

I know that is hard to read, but I wanted to add it up. In that 24 hours, he slept 16.25 of them! For Branson, this is a ton. He has started to do lots better about sleeping in long stretches too, which is great for me. Thanks little guy!
