Q: Hi there I am a mom to a 7 week old, and initially his day sleeps were fine, textbook however in the past couple of weeks i cannot get him to sleep longer than 45 mins at 11am. He sleeps for an hour in the morning - anywhere from 830am - 10am. Then 45 mins from 330 / 4pm. However he wakes after 45 miins of sleep at 11am. How long should he be sleeping for? This really does not give me enough time to rest during the day. At night he is a champ. We bath at 6pm, have some food and then asleep by 7pm. He will then wake anytime from 1am - 230am. And then again at 5am (thinking its playtime). So routine...
