Since about 16 months he's been waking between 10pm and 2am and I've been so tired he's just been brought into our bed for some sleep.
Very occasionally (3 or 4 times in 10 or so months) he will sleep all night in his bed.
Last night was one such night - is there any way I can capitalise on this success to try and make it happen more often? When he woke I told him what a good boy he was and gave him a sticker. And spent time during the day talking about how good he was to sleep all night, and reminded him at bedtime! But I did all that the last time he did it and it made bugger all difference....
