DS used to be an amazing sleeper, but he hit five months and everything has gone to hell. His sleep is now completely erratic, but the most common thing is for him to wake at about three or four and refuse to go back to sleep. He's cried for two hours tonight while being held, cuddled, rocked, until we've finally given up and got him up for the day. He will now be hideously overtired all day.
He's not hungry. The room is warm enough, dark enough, etc. What do we do? I'm due back at work soon and I just can't cope on this schedule. How do I manage daytime naps when he's been up since 3? Do I let him sleep as much as he wants or wake him up so he'll sleep at night?
Please help!
