In this episode, Katie James and Johanna Sargeant explore the rise of silicone milk catchers (passive pumps) — those popular “milk-saving” gadgets showing up in baby showers and new-mum starter kits. They unpack how these tools work, why so many of us 'love' them, and the hidden risks that can quietly tip a normal milk supply into oversupply. Through real clinical experience and stories from their work with thousands of families, they explain what’s really happening in the breast, how oversupply impacts both mother and baby, and what to look out for before adding a milk catcher to a breastfeeding experience. It’s an honest, research-informed conversation that balances science with empathy — and offers practical, judgment-free guidance for both mums, parents and professionals. Takeaways Silicone milk catchers can help collect milk, but they also apply some vacuum pressure. Early use may disrupt natural supply regulation and lead to oversupply. Oversupply can cause feeding difficulties, inflammation, and stress for both mother and baby. Breastfeeding is a relationship — not just a method of milk transfer. Waiting until around six to seven weeks postpartum allows milk supply to stabilise naturally. Not every mum needs a milk catcher; support should be individualised. Real success comes from informed, flexible feeding — not gadgets or rigid rules.
