Possums Breastfeeding & Lactation (PBL) FOUNDATIONS

How babies breastfeed 1. Short animation; 2. Video + animation

The mechanical effects of nipple + breast tissue drag on breastfeeding

Mechanical pressures are the engine room of breastfeeding and lactation

What causes your breast to become inflamed when you're lactating?

Why your letdowns help prevent or heal inflammation when you're lactating

PBL INTERMEDIATE

The mechanical effects of nipple + breast tissue drag on breastfeeding

Your nipple skin knows how to adapt to the mechanical pressures of breastfeeding (or pumping)

What causes nipple pain when you're breastfeeding or lactating and there's no visible break in the skin (though there may be redness and swelling)?

What causes visible nipple damage (cracks, ulcers, bruising, or other wounds) when you're breastfeeding or lactating?

PBL ADVANCED

Mechanobiology: a frontier science which explores the effects of mechanical pressures on living tissues

The difference between biomechanics and mechanobiology in breastfeeding and lactation

Knowledge of mechanobiology is essential for clinical management of breastfeeding and lactation-related problems

Ultrasound and vacuum studies elucidate the biomechanics of the infant suck cycle in breastfeeding

Intra-oral ultrasound and vacuum studies of breastfeeding infants support the mechanobiological model of lactation-related nipple pain and damage

An ultrasound study demonstrates how the biomechanics of infant suck change after a gestalt intervention

The Watson Genna et al 2021 study of the biomechanics of infant suck in breastfeeding has serious limitations

NDC mechanobiological model: hydrostatic stretching and compression acts as a mechanical Feedback Inhibitor of Lactation, downregulating breastmilk secretion

Clinical inflammation of the stroma of the lactating breast: NDC mechanobiological model

Milk ejection causes asynchronous ripples of pressure change throughout the breast stroma

Skin adapts to protect against mechanical forces

You don't need an in-depth knowledge of anatomy, physiology, mechanobiology, or histology to provide evidence-based, state-of-the-art clinical care for breastfeeding and lactating women.

But there is some foundational knowledge which helps make sense of what is likely to be most effective in clinical breastfeeding and lactation support (when we lack proof of efficacy, which is the case for so much of what we offer when helping lactating women). For instance, if you want to understand why the NDC management of milk production concerns or breast inflammation are different to current models, and why NDC lactation clinical practice seems different overall to standard clinical approaches, then you need a solid understanding of functional anatomy and mechanobiology.

The principles…

Possums acknowledges the traditional owners of the lands upon which The Possums Programs have been created, the Yuggera and Turrbal Peoples. We acknowledge that First Nations have breastfed, slept with, and lovingly raised their children on Australian lands for at least 65,000 years, to become the oldest continuous living culture on Earth. Possums stands with the Uluru Statement from the Heart.
