11 month old waking up constantly/feeding for comforr

Our lovely girl has been a terrible sleeper since around 5 months. Before that she did decent stretches. On a bad night, shesleeps for 2 hours then wakes every hour, only going back to sleep after conforted by boob and falling asleep feeding. On a good night, we get a couple/few hours between wake ups. I’m sure feeding to sleep has created a habit and undure how to gently change things. I’m exhausted! Any advice? She eAts lots of solids/lots of breast milk so not hungry
