I am a low yield bm mother who is supplementing my baby with fm once/twice per day. I am trying to let baby latch as much as possible and pump 4 hourly. My baby sucks almost 1-2 hourly with no standard timing/ schedule. Sometimes even shorter interval. Problem arises when baby cries when it's about my time to pump, making me to miss my pumping session. Anybody has the same problem with me? And how do you cope with it?

Sounds like you're feeding on demand which is okay if you have all the time to focus on your baby. However as busy mothers, this is not the most ideal plan. Since you're already supplementing baby with fm, why not take the opportunity to pump when she's drinking from the bottle. You can also try pumping when baby is napping. Take this opportunity to steer your baby's feeding schedule to be more of a structured routine. It will definitely make nursing and pumping less of a challenge. Good luck :)
