How can I wean my toddler from breastfeeding?

My toddler turned 3 this year and she is still wanting breast to sleep but she only does this when I am around…she goes to school and falls asleep by herself for naps I feel ready to stop breastfeeding but she is still waking up at night to drink I’m not sure how to go about this if any of you have had this experience before, I could really do with some ideas or even just to know that it’s some sort of normal and not a societal norm
