I didn't night wean until 18mo. But, I also would only nurse once during the night after 1yo, they got cuddles and water if they woke more than that. (edited to add, all of my kids also had pacifiers, which helped alot, they were all marathon sukcers and if I let them, they would have been attached to me all day! lmao) Many babies younger than 1yo cannot go all night without being fed, their stomachs are too small, so I always fed on demand up to a year, and then started setting boundaries after that according to their needs and my limitations. Every child is different, but if your baby is waking up that much, she is probably still hungry, her primary source of nutrition up to a year old should be breastmilk, so waking up to feed, if your baby requires it, will probably be necessary for a few more months.
I simply don't believe in letting a baby starve. Nightweaning when they are older is much easier and less traumatic for everyone. Try to nurse more during the day and give a solid food right before bedtime, that worked well for us. Solid food right now is really only "for practice".
Also, her needs change according to when her growth spurts are happening. Right before one, she will need the most calories and you will notice at some point she is sleeping more, which is a cue that that is the "spurt" time itself.
Also, we did the family bed, so that helped night wakings be much less disturbing to everyone. All I had to do was roll over and feed, my babies actually cried very little during the night because I was right there to comfort them.
Do what you feel is best. I know how tired you are, I had four kids in 7 years, and it felt like I didn't get a full nights sleep for...well...forever lol! Nap during the day when you can, and be gentle with yourself. You deserve it :)
