I have a 15 month old son who will go to bed fine in the evening but is waking up at 4.30 every morning, he goes to bed between 7 & 8, Previous to this he always woke at 6.15 more or less on the dot how do I get him to sleep through again? Also he refuses to go to sleep in his cot in the daytime and yesterday managed to climb out of his cot, so now i am thinking of putting him in a bed, will this make his getting up worse?
