How to stop breastfeeding

My daughter is 16 months I am so ready to be done breastfeeding I feel exhausted. But it feels impossible... she nurses many times through the day.....(and night) especially to sleep for naps and bed time. Refuses cows milk almond milk. How can I make this happen ☹️ I try to start but then I feel like I have to keep nursing because I was told by doctor you can't quit while teething??? Ugh any tips are appreciated
