My son is 26 months. He was always a good sleeper until he turned 2. Now, he is up about 2 - 5 times a night. We followed the Healthy Sleep Habits, Happy Child book. When he gets up, we just pick him up and put him back in his bed. He goes without protest. Maybe I shouldn't complain, but I just want him to stay in his bed all night. So, I need help. How can I get him to stay in his bed all night? If he is waking, what can I do to get him to fall back asleep on his own? We've been given some suggestion's - lock his bedroom door, or use a gate. Neither of those are opitions. Please help... I'm pregnant again, and tired...
