My son is 13months and we have started to leave him in the middle of night - 4am to cry himself back to sleep. I am going mad - I know he has to lurn to fall back to sleep on his own, but is there an easier way??? Last night was our first night and he cried for 20min and then I didn't sleep all night wondering if he is ok. Needless to say he woke up 7.30 refreshed and very happy! Any thoughts on this matter will be helpful.
