Как отучить 17-месячную дочь от грудного вскармливания?

Hey lovelies i really need some advice on something. Ive got to a point where i really dont know what to do. Its to do with Breastfeeding. Violet is 17 months old and ive wanted to stop breastfeeding when she turned 1 but it just never happened. She only feeds on me for a nap in the afternoon but nighttime is more my issue. When she was younger and i was constantly getting up to feed her, i became so tired, so one time i just brought her into bed and fed her while i could lie down. I have completely regretted it ever since as it became into violet sleeping in the bed with me ever since. She refuses to sleep in her cot. She will only go to sleep if she is with me. Plus shes 17 months and she still wants to feed at night time. But i think its more of a comfort thing. So throughout the night she wakes up for boob and then goes back to sleep. But its like all through the night. Im exhausted. It cant continue, i just dont know where to start to stop this and get violet sleeping in her own bed and not wanting boob.
