I think you have your priorities back to front. Most people ween because they themselves are over breastfeeding. That can't be the case or you wouldn't be feeding your husband. Your husband doesn't need it. It's just a fetish for you both (and tbh as such doesn't really suit this part of the forum as it is sexualising breastfeeding) but WHO recommends BF till 2. Surely your Childs feeding needs come before a sexual fetish?
