Have you been fitted for pump fl**ges in hospital recently?
Chances are, you may have been incorrectly sized.
Today we are talking about the latest on pump fl**ge sizing.
In the birthing sites I work in, the Medela pump fl**ge sizing tool is still used. Medela pump fl**ges come in sizes 21mm through to 36mm.
This is a problem.
Research on sizing shows that most mothers/lactating parents will fit somewhere between a 15mm and 19mm. The Medela tool does not accommodate for the majority, so pump fl**ge sizes are almost always too big in the hospital environment.
My trusty silicone b***y has an average sized ni**le.
Even the smallest hole in the Medela sizing card is too big.
We no longer upsize or add mm to the size of the ni**le, as suggested on the Medela card.
So, keep in mind, even if you have been measured up, that measurement is restricted to the equipment that is available and the education of the health professional measuring you, and may not be a true reflection of your sizing.
Ni***es come in all different shapes and sizes, and if you do fit a larger size, you are still perfectly normal!
With my other hat on, as a BFHI (Baby Friendly Health Initiative) Coordinator, I am undertaking a quality improvement project to improve access to pump fl**ge sizes in hospitals and provide education to midwives in measuring accurately.
For more detailed information, the Babies in Common "Fl**ge Fits Guide" is a great resource.
