Gradually weaning is much better then going cold turkey…your breasts thank you! Your instincts are correct. The fact that you have a lower supply may help you in this catagory. I would start eating peppermint altoids or peppermint tea as this alone will bring down your supply. If you are pumping at all, I would stop and stick to just feeding. I would start by eliminating the middle of the day feedings first, as this is when babies are more likely to not notice. So for example if you have been feeding 4 x a day, pumping 2 x a day. Start gradually.
week 1. Continue to feed 4 x a day, eliminate all pumping
week 2. Feed in the morning, skip middle of the day, feed late afternoon, and at bedtime.(no pumping)
week 3. Feed only in the morning and at bedtime (no pumping)
week 4. ( decide which ever feed your baby enjoys more evening or morning, and keep that one eliminate the other.) Do this for 3 days, then by day 4 begin the cabbage treatment as stated in the article. By the end of the week you should be dried up. If you experience engorgement cold compresses and Ibuprofen will help. Good luck
