weaning

If you are conciously weaning your nursing baby, what is that looking like for you? My son is nursing four times per day, and I am trying to cut out the late am nursing session and replace with some formula. I can't remember what I did with my other two, but I do know that it naturally went to three times a day around this age, then I started giving them some milk when they were almost a year. In starting a little earlier with him.
