Sick little boy

Our boy has a sinus infection but has been playing as hard as he can through it and skipping his naps or taking very short ones until last night. He finally decided he needed to sleep. He laid down at 4:30pm for his nap and decided he was down for the night. He woke for short spurts during the night but never cried or wanted out of his crib, he just played for a little while with his music toy in the crib and went back to sleep. It is now 9:00am and he just woke up. Wow what a way to make up for lost sleep. Now if his sister would sleep like that we would have it made.....
