How to establish good baby sleep habitsonce your baby is about 2 weeks old, you can start teaching him to distinguish night from day.
When he's alert and awake during the day, interact with him as much as you can, keep the house and his room light and bright, and don't worry about minimizing regular daytime noises like the phone, music, or dishwasher. If he tends to sleep through feedings, wake him up.
At night, don't play with him when he wakes up. Keep the lights and noise level low, and don't spend too much time talking to him. Before long he should begin to figure out that nighttime is for sleeping.
