Breastfeeding help

al

So I’ve been breastfeeding my son now for 20 months he’s just about to turn 2 he’s drastically weaned to 2 feeding a day and one at night sometimes one a day or just a few sucks as a snack between meals. I have loved every single moment of breastfeeding and I don’t want it to end but he’s weaning himself should I just let him continue to wean himself or just cut him off? My breasts don’t make nearly as much milk and I hardly ever feel full anymore.
