Are they sleeping through the night after that feed? If so, what time are they waking?
Like noreneh says, there's no easy answer... with my first, he slept through from about 6 weeks old. But I did have to feed him around 10 or so. Then he'd wake around 6 or 7 (I think... it all becomes a blur now!).
With my second child, however, feeding was a nightmare and I posted about it all. the. time. on here. With him, I made no progress until he could find either his pacifier or a bottle on his own in his bed. That was around 9 months. It sucked and I was reduced to being like the living dead.
So, at worst case scenario, I'd say you've got another 4 months to go.
