my friends babies are all sleeing through the night. Yet my 6mo DS will only do it once in a blue moon. It seems to be only when he has stayed the night at someones. When I get him back he goes through the night for about 4 days after! after that he goes back to his old ways! I know he is capable of going all through- so what am I doing wrong??
Is there an age where they should be big enough to go through?
