My DD was a seriously frequent night waker too, and always fed (BF) back to sleep - sometimes co-sleeping, but more often in her own cot. With minimal intervention (we were too tired to try any techniques and definitely didn't want to CIO / CC) she eventually slept through at 16 months. We had a horror stage at 12 months where she was waking & feeding hourly, but then between 13 months and 16 months it gradually improved til she was sleeping 7-7. so, yep, sometimes the tunnel is long but there will be a light at the end!
This pretty much sums up my experience with my DS, except he was 18 months when he started to sleep through. He sleeps now for about 11 hours at night.
He sleeps (and always has) for about 4 1/2 hours during the day and i was thinking that that could be related to him sleeping less at night, but his day sleep hasn't been affected at all.
As a PP said it just goes to prove that they will do it when ready
