Sleeping through the night!?!

Last night, we fed Gavin a little after 10 like we always do and then put him to bed. He was getting up to eat at 1 and 4 most nights. For several nights in a row, he was stretching it out to 2 or 3 instead of 1. Last night, he didn't wake up until 4am! I couldn't believe it. He slept for about 5 1/2 hours! Technically, 5 straight hours is considered sleeping through the night. Although I look forward to the night he doesn't wake up until 6 or later, I am thrilled with how well he is doing. As many of you know, Macie still doesn't sleep well most nights, so we feel so blessed to have a little guy who sleeps!
