Kate Sharp and I were the originators of the pump about every waking 
hour for 24-48 hours variant of powerpumping (it was named by Leigh Anne 
O'Connor). It was designed for mothers whose infants are in NICU or 
nonlatching. To make it possible to do, we recommend they do it over a 
weekend or when they have someone to help them with everything else, 
keep the pump in the living area (or wherever they spend their time), 
and use it every time they have a few minutes. For full term infants, 
cleaning the kit every 4-6 hours, for preterm, having 2 kits to minimize 
the barrier of cleaning everything is important too.

If mom already has a bf baby, I usually recommend supplementing at the 
breast and expressing after bf (and possibly between feedings if baby 
typically sleeps a long time), for exactly the reasons you mention, Laurie.

And no, we don't have any research on effectiveness. It started as a way 
to problem solve pumping and help moms get milk removed frequently, to 
mimic the baby cluster feeding for a day or two to increase milk 
production. It's not going to work if the pump isn't effective, so we 
need to do that work first.
