Hi. Wow, 19 months of breast feeding is amazing. My girls didn't want to nurse past 12 months. If you are wanting to dry up your milk, the best and fasted way is to put raw cabbage leaves in your bra. This will make you leak so be prepared. Otherwise, you just do not stimulate your breasts at all and it will dry up on its own. This is a more painful process but will work in a week or two. Good luck!
