DS was like this. He was very unsettled early on and it was the only way to get some sleep. He settled down a lot by around 3 months, and we started using some tips from the No Cry Sleep Solution to get him sleeping on his own. It worked. But then the next 'thing' came along and we were back to square one. He was over 2 before he was able to go to sleep by himself and sleep all night. It has stuck since then.
