My baby has only just started crawling in the last week. She's been on one nap most days now for a while. At night she goes to bed at 6 and often sleeps until 7:30. She very rarely wakes before 7 and has a 2.5-3 hour nap from about 11/11:30.
She was sleeping well before she started crawling, but not this much. She's not sick or anything. I do worry, though.
