If your down to 3 times a day and he is doing well he very well may self wean in the next few months. My daughters both did shortly after the nursing became not so much food as comfort. I would first cut the am feeding then when he is ok with that then the nap time feeding. Give him a sippy cup with milk or water instead and cut out the bed time nursing last. If he is sick , hurt or upset and nursing for comfort try just snuggling with a favorite blanket, animal or whatever. A.
