I know this is debatable with some people saying from 1-5 is sleeping through the night but my ds was put to bed at about 8ish and is still asleep. he normally wakes up at 4 for a feed. also I normally give him a dream feed about half 10 but the past two nights I've been that tired I've fell asleep before then and he hasn't woken up for one.
so instead of enjoying my unbroken sleep I'm up shocked he has slept all night :O
