I don't know what sort of food she's eating at the moment, but I wouldn't be confident to rule out hunger until she's on 3 proper meals a day, including proper protein like meat , and also bulky carbs like pasta.
If she's still at the fruit / veg puree stage, then that's not going to fill her up for long.
IMHO I would continue encouraging her to learn how to settle herself to sleep when she goes down for naps, as this will help her go back down quickly after a feed at night. It'll also help her resettle herself at night if she wakes for a reason other than hunger
I wouldn't be confident to withdraw night feeds until she's properly established on solids though.
Once you get to that point, if you're breast feeding, try to make each night feed shorter by about 5 mins every few days.
If you're formula feeding, you can either make the feeds gradually smaller, or you can water down the formula gradually.
Structure her daytime food and milk so you know she's getting everything she needs during the daytime.
Then, if after all that, she's still waking up, then it might be time to try controlled crying. For me though, that should be a last resort, with every other avenue tried first.
Does she have a dummy? Will she settle at night with that instead of a feed??
I know it's exhausting though - I feel for you!! I found night feeds much more bearable once I got to the stage when i could feed my ds, then put him back down awake and we'd both go back to sleep without each other!!
If I were you, I'd concentrate on getting to that stage for now, and maybe look at dropping the feed completely in another month or so, when solids are properly established.
