Q&A: Switching Up Nursing Positions?
It's a myth that you need to periodically change nursing positions in order to fully drain all of the ducts in your breast. In reality, when your baby nurses, your body triggers a let-down reflex that pushes the milk forward in the breast and allows it to flow as your baby drinks. This let-down pushes milk forward in all of the ducts, and they all drain as baby nurses, regardless of the position baby is in as he drinks. So if you’ve found a comfortable position that works well for both of you, there is no need to change; however, if you're still looking for the most comfortable position, experimenting with different ones at different times can be helpful in finding what works best for both of you.
