double pumping

Also: simultaneous pumping, pumping both breasts, double expressing

Pumping both breasts at the same time instead of one after the other. It saves time and is widely taught in lactation care.

In plain words

Double pumping means pumping both breasts at once, using two flanges on a double pump. It is the usual way mothers pump, because it saves time. Many mothers find it gives a similar or larger amount in less time than pumping one breast after the other. Some mothers combine it with or breast massage during the session. Comfort matters. Pumping is not meant to cause sharp pain, and bruising or nipple damage can mean the fit or settings need a change. A can teach the technique and check the fit. Mothers who pump at work or during a period of low supply often use this method.

The deeper version

Simultaneous double pumping is supported by studies showing comparable or greater milk volume per session relative to sequential pumping. Prime and colleagues (International Breastfeeding Journal, 2012) reported elevated response and efficiency during simultaneous expression in exclusively breastfeeding women. Morton and colleagues (Journal of Perinatology, 2009) found that combining hand expression with breast pumping increased milk volume in mothers of preterm infants. Hands-on techniques, simultaneous double pumping, and use of the are widely taught, and the evidence for maximum comfortable vacuum is stronger for comfort than for volume. The open question is how much technique changes long-term supply versus short-term output.
