Tips for weaning breastfed toddler

My little one is 2 and half, I’m so proud of myself for making it this far after all the complications we had latching during the newborn stage. But it is getting very uncomfortable for me and I feel so guilty! Especially with all the incredible benefits there are for mama and baby. Any tips to help us start weaning her off slowly?

I should mention she is a baby genius, we’ve tried so many tricks we thought would urge her to stop but none worked. One including a charcoal face mask on my nips to try to convince her that it rotted. She wiped it off with a baby wipe and continued as normal. I’ve heard of the vinegar trick but am very hesitant to try because I’m afraid of it burning her throat!
