Interesting info, Cindy, thank you.
Is it  me, or does 200 hours seem like it doesn't match the time amount a
mother who wanted to pump to give her baby her milk for 12 months. might actually
be spending..
Back to work at 8 weeks, means 10 months of pumping, from 2 months to 4 mom
might be pumping perhaps (9-5 job, means 8-6 away from the baby), 10 hours
away, pumping at least 3 times/day at work, 5 days a week, 15 minutes ( 1/4 hour)
at a time =15 times/week for 1/4 hour each = 3.75 hours/pumping./week for 8
weeks = 30 hours until month 4. Between month 4 and 12 ( 8 months, or 32 weeks).
mom might be pumping 2 times/day for 5 days/week for 1/4 hour each time = 2.5
hours/week for 32 weeks = 80 hours. Add the 30 and the 80 = 110 hours of
pumping. This is if the mom has not pumped in the early months because
breastfeeding was going well. IF the mother has a baby who can't latch due to anatomical
structure challenges, for instance,  then she might be pumping 8 times/day (
more at some points)  for 1/4 hour each /7 days a week for 8 weeks before she
returns to work. That comes out = 112 hours in those first two months. Add that
to the 110 after the return to work, ( assuming the baby can actually
breastfeed well and exclusively by 2 months) and the pump has been used 222 hours,
which is over the recommended functionality for this kind of pump. For mothers
who have already bought the pump, and refuse to rent ( because the one they
have seems to be bringing in a good milk supply even when their baby can't) in
those early weeks, does this mean that at some point in that first year, this
pump might fail or at least function less efficiently? Is this something LN
people have seen happen? Pardon me if the math was off, but it seems like we do
see these pumps performing less efficiently sometimes down the road. I wondered
if the mother's body responded better to the baby, or the baby's stimulation
was just so distinctive as months pass that the body didn't respond as well to
the pump, but perhaps it may be actual pump fatigue as well?
Also, could Fritzi clarify what she wrote:  " Hospital grade pumps also
differ in that although they may reach as high a  vacuum peak, they do not sustain
it as well,and as smoothly, and thus do not  provide as high of a prolactin
and oxytocin surge to then stimulate a sustained  long term milk supply."
This makes it seem like the "they" refers to the hospital grades, do you mean
"they" as in the smaller pumps not sustaining a vacuum peak as well/smoothly?
I may have just read that wrong, since it doesn't make sense to me...
Just musing,
