Not sure if I can help you, but how much time do you give him to settle himself? My lo fusses before she sleeps, and I lay her down, and leave the room, she fusses and then tends to go to sleep, in five, sometimes 7 minutes. Do u rush in everytime you hear him wake up. What kind of cry is it? Is it more of a mantra cry, or "come get me now" kind of cry? What kind of schedule is he on? What time does he go to bed. When our lo started waking up for an hour at night, a few weeks ago, we tweaked her bedtime a little, and instead of 7, she now goes to bed at 7:30, and slleps thru' the night. Maybe your lo also needs a little less sleep. How does he do for naps?
Let us know, and I'm sure, someone will be able to help.
