Hi my son is 3 and he has given up his dummy about 4 weeks ago for sleep. It only took one night and he has never asked for it again which is great! BUT he has gone from a great sleeper who slept undisturbed all night from 7pm until about 8 am to now waking 3/4 times a night crying we go in and he does quickly settle again but he either asks for water or says he doesn't know what's wrong. He then is getting up about 630am. About the same time he dropped his daytime nap. He is now only sleeping during the day if we r in the car...any advise to improves things? Thanks
