Though extremely useful when I working mum, they are not nearly as efficient as a baby for expressing milk, and make a hell of a lot of noise. I’m stood here In the bathroom, hooked up and feeling distinctly like a cow. The thing even makes mooing noises!
Note to breast pump makers! Please REDUCE sound so that it’s not so embarrassing to do this, or create a more pleasing one. Women all over the world have to use these and don’t have special rooms to do it in. Public bathrooms are less than forgiving when you hear moos from a cubicle!
