Pumping should be simple. But for many mums… it becomes painful, confusing, and ineffective.

In this episode, Katie and Joh unpack what’s really going on when pumping “isn’t working” — and why the answer is rarely what you think.

Episode Summary

Katie and Joh take a deep dive into the reality of pumping, starting with one of the most overlooked issues in lactation support — incorrect flange/shield sizing. They explore why so many women are given the wrong size, how this affects comfort and milk output, and why going smaller, not larger, is often the key to effective stimulation.

The conversation moves into pump types, including hospital-grade pumps, double pumps, and wearable devices — where, for once, Katie and Joh don’t entirely agree. They explore the tension between efficiency and flexibility, and how the “best” pump depends entirely on the individual mother, her circumstances, and her goals.

They also unpack practical strategies to improve pumping outcomes, including timing, vacuum levels, switching between stimulation and expression modes, and why watching milk output can actually reduce it. Joh shares the now well-known “sock over the bottle” technique and the surprising impact of removing visual pressure.

Finally, the episode broadens into the emotional and psychological experience of pumping — from stress, grief, and NICU experiences to the importance of oxytocin and creating a sense of safety. They highlight that pumping is not just mechanical — it is deeply physiological and emotional, and support must reflect that.
