In the past three weeks DS has been waking several times in the night, sometimes as early as 10.30pm, and been impossible to resettle. The only thing that works is bringing him into our bed where he promptly falls asleep and sleeps through until 7.30am. This usually means DH ends up on the sofa because he finds it hard to sleep with a large, sprawling, wriggly toddler in the bed. I want DS to sleep all night in his own cot again. In general I would say he's been a pretty normal sleeper and we've let him develop at his own pace rather than do any serious sleep training. I don't expect him to sleep for 12 hours straight every night. We did night-wean him at around a year, and occasionally have done a light version of controlled crying - comforting every few minutes. He has a 1-2hr nap around lunchtime and is generally very active. He goes to bed in his cot around 7.30pm no problem. Does anyone have any experience or suggestions to get out of this new habit? Thanks very much!
