My personal challenge is that although my 4 month old sleeps through the night decently, he doesn't wake up at a consistent time. So, I feed him when he wakes up, which could be anywhere from 5:30 - 7:30. I try to do the 4 hour EASY, but his naps are only 40 minutes which completely throws off everything. PLUS, the 4 hour EASY is inconsistent due to the inconsistent wake up time. Any help would be really appreciated! One other thing, because he isn't sleeping enough during the day, he keeps pushing for an earlier and earlier bedtime...I have to deal with tons of crankiness to get him to have a bedtime of 6 to 6:30.
