I had the same issue with DD1 at the same age. I would feed her to sleep for all naps, bedtime, and night wakings. I was getting up every hour or more and thank god I didn't have toddlers. What broke the cycle for me was patting her to sleep for her day naps. It took a couple of minutes of grizzling but I couldn't believe it worked! It taught her to fall asleep without my boob and she instantly went to only waking twice a night. But luckily she was quick to settle so I could deal with that. I never did the patting at night because it involved a lot of crying which I hated.
