Dear Lactnet Friends:

I don't know of any research comparing the health impact of breastfeeding
versus pumping on the mother's health.

There is research showing that breastfeeding is more beneficial for the
infant in terms of reduction of risk for asthma. (J Pediatr 2017;190:192-9).

The backwash from baby's mouth into the breast plays an important role in
the antibody formation that helps protect baby. This won't occur with
exclusive pumping.

"Researchers found that breast milk from women who pumped tended to have
more potentially bad bacteria -- and less abundance and diversity of
friendly germs -- than milk from women who only fed their infants from the
breast." "A large-scale analysis in humans reveals that indirect
breastfeeding using pumped milk is associated with the depletion of oral
bacteria and a higher abundance of potential pathogens compared with direct
breastfeeding at the breast. The findings, published February 13 in the
journal Cell Host & Microbe, large-scale analysis in humans reveals that
indirect breastfeeding using pumped milk is associated with the depletion
of oral bacteria and a higher abundance of potential pathogens compared
with direct breastfeeding at the breast. The findings, published February
13 in the journal Cell Host & Microbe,"

Other research shows that babies bottle-fed breast milk are in the middle
of obesity risk: highest is those bottle-fed formula, and lowest is the
breastfed infant.
"The benefits of direct breastfeeding included slower weight gain and lower
BMI scores at 3 months, according to a Canadian study published Monday in
the journal Pediatrics 2018.  Still, even pumped breast milk was superior
to none at all, in line with past research."

In the US, there is no paid maternity leave. Pumping may get a baby more
mama milk than no pumping.

It's another benefits/risk trade-off.

warmly,
