My son has been having trouble sleeping for two months. We've been struggling for almost eight hours, crying and he only falls asleep for 5-10 minutes at a time, then wakes up and keeps going for an hour. I walk around holding him, even though he's full, but he still falls asleep at 2 am. Almost everyone does this, so I'm exhausted.
