Good Morning A.-
First off koodos for you to nurse your baby for this long.... My hat goes off to you and you will see the immune responses as she gets older. Since your toddler is 16 months old, you are right and she can be weaned cold turkey and be fine. The problem is you more than her. It is also possible to quit cold turkey without seeing a lot of problems if you are very careful. This is why we have some women do the "girl's getaway weekend" when they are trying to wean a smaller baby. Instant weaning does not mean breast infection, but it can mean a little discomfort. First off, if you do not have an allergy to asprin, I would 1) take 3 200mg = 600mg Ibprofern every six hours during the process. 2) I know this is going to sound crazy, but it works...... Go and get some cabbage and freeze it. Wear it in a tighter bra (like sports bra instead of nursing bra) around the clock for about three days. Does not make for much romance the smell, but it does work. When it becomes wilted, change the leaves to new ones. 3)Stay away from your husband romantically during this three to four day process. They help encourage milk production believe it or not... 4)Take some Benedryl at night; if no allergies ~ the antihistimine helpd dry up the production. It works.
You may be able to still produce milk even though you are not truly producing enough to make a huge difference. I hear women all the time say, I am still lactating after weaning three months ago.... What's wrong? The truth is, just because you may be able to squeeze and produce milk from your breast, does not mean you are still fully lactaing. Some women can do this for years after weaning and some after an abortion. If they were to pump, it would only be drops there, so squeezing to see milk does not mean your body has not responded. Good luck with the journey of baby #2.
