How do i stop breast milk, because i want to get my baby off breastfeeding when he is a year old?

Three basic plans: Cold turkey: bind yourself & send baby to others to bottle feed until they will for you.(painful & frustrating for both but some do ok.) gradual: drop a feeding every day or two, using bottle instead. At some point body drops supply & you can accelerate coming off. (less pain) some also use baby to soften a tense breast but follow with a bottle each feed.This tells the breast to slow production.
