A little extra detail about Breast Shield Convertors (Breast Pump Flange Sizing Inserts):

What size convertors do I need?

You can use our Size Quiz to find your recommended size. Alternatively add 1-2mm to your nipple base measurement (do not include areola). For example, Sam measures 15mm on one nipple, 16mm on the other, so size 17mm is the recommended size convertor. You might not need a convertor if your size is a standard breast shield size.

What convertors will work with my size breast shield?

Size 26 convertors fit in size 28 silicone breast shield. Sizes 22 and below fit in size 24 plastic or silicone breast shields. These won't work with Youha silicone massage cushions.

Why are there two different shaped convertors here?

For those who are a bit smaller than the Youha convertor range and need size 15 or 13 convertors, we've stocked up on the fantastic Milky Business flange inserts. Milky Business use a slightly different design but perform equally well.
