Since Brennan got sick last Sunday, he's been sleeping through the night. Granted, when he was sick he was sleeping A LOT...like 12 hour stretches, but since he's been better he's averaging 6-8 hour stretches with more of them being 8. Yay! I'm almost back to a normal sleep schedule!
Brennan started much earlier (about 4 weeks earlier than Colin), and with Colin we forced it. We just let him cry. So far, Brennan is doing it all on his own!
