I was right about the sleeping last night. He went to sleep around 9:30 and slept all the way till 5:30 this morning, when he sucked down 4 oz in about 10 minutes and fell back to sleep till 7:30, ate a bit more and then slept till 10:30. And today he had an 8 oz bottle right when he got up, we played for awhile on his new play mat, played Peek-A-Boo and looked in a mirror for awhile, had some juicies and now he is asleep again, almost 2 hours to the minute from when he woke up, he is down for his nap. I guess I should mention that Misters usually only eats a 4 oz bottle, and then SOMETIMES he will have another couple ounces if he is still a little hungry. So you have to understand that he is eating double to QUADRUPLE what he usually eats at a time. And he slept for 13 hours, 12.75 hours if you count the eating, but he wasn't exactly awake... If this isn't a growth spurt I don't know what is!
