Sleep Training

So as many of you know I started sleep training a few weeks ago. I thought for sure that when we went to Oklahoma to see Brian that it would set me back in the training. But when we got back he went to bed at the normal time very easy. I was so proud of my little boy. Now if I could get him to stay a sleep but his problem time period is anywhere from 12am-3:30am, he'll wake up and than sit up and say "mum...mum...mum" until I come down there and put him in bed with me. So I've been sleeping on the couch for a little over a week. I hope that he'll stop calling for me. It would be nice to sleep in my bed again.
