The Mommy Material Freely Silicone Inserts are replacement fit inserts for the Freely Electric Wearable Breast Pump. They sit inside the pump's breast shield to reduce the tunnel size, so if the standard flange feels a little roomy, an insert can bring the fit closer to your own nipple dimensions. Made from soft, BPA-free, food-grade silicone, they cushion the seal against your skin, which helps keep expressing comfortable.
Fit is one of the biggest comfort factors when you're pumping, and it isn't something you can reliably guess from bra size. These inserts come in a choice of breast shield sizes so you can dial in a more personalised fit — a snugger, better-aligned seal that tends to feel gentler and helps the pump hold its vacuum. If you've found the wearable pump slightly uncomfortable or not quite sealing the way you'd like, a different insert size is often the simplest place to start.
Finding your size
The inserts are available in 19 mm, 21 mm and 24 mm, so you can choose the option that best matches your nipple diameter. It's worth taking the time to work out your measurement rather than defaulting to the standard size, since a well-matched insert is what makes the difference between a comfortable session and a fiddly one.
Caring for and replacing your inserts
Silicone is a soft, flexible material, and like all soft pump parts it wears over time. Check your inserts regularly for any signs of stretching, tearing or general degradation, as worn parts can affect how the pump performs. Mommy Material recommends replacing the silicone inserts every 2–3 months, or sooner if you notice any wear.
Best For
The Mommy Material Freely Silicone Inserts are a good option for parents who:
- Use the Freely Electric Wearable Breast Pump and want a more personalised fit
- Find the standard breast shield a little large and are looking to size down for comfort
- Need to refresh worn soft parts to keep the pump working as it should
They won't fit other pump systems, so they're only suitable if you're using the Freely Electric Wearable Breast Pump.
