Liebs stopped at about 10 months with the night feeds, but that was because he wasn't interested in feeding but rather playing when he woke in the night.

He stopped waking at night for water (right next to his bed, but screams until I hand it to him)/loo (screams until I take him, despite being able to walk himself)/too hot/too cold/nightmare/just woke up and so on... well, I'll come back and update when he does for at least five nights in a row. He's six and a half years old now.
