Once Colby turned a month old, I decided to stop waking him up at night and see what happened.
The first night, he slept for five hours and then woke me up to eat. He went right back to sleep and then slept for another four hours.
The second night he slept for five hours, woke up and eat and then went right back to sleep again and slept for another three hours.
The third night (last night), Colby slept for seven hours before he woke me up to eat. Then he went back to sleep and slept for another four hours before he wanted to eat!
Hopefully he continues to sleep well at night :)
Another big milestone.... Colby has started to smile! I've tried to get a picture, but haven't been fast enough.
