My DS is 17 weeks old and has started waking up at random times through the night making chunntering and wimmpering noises. He isnt hungry and is sometimes only half awake. We leave him to settle and sometimes it takes him 5 mins and sometimes he wakes up completely and starts crying. He actually started sleeping through from him 11pm feed last week and has now regressed completely to this awful multiple waking situation. Has anyone else had this problem? any tips on how to help the little fella settle himself and not keep waking?
