Look at research at Australian Breastfeeding Lab. Where baby vacuum measured with strain gauge and milk volumes measured.

Do I understand you well, Gonneke... do you question the research about the necessity of a vacuum, research sponsored by a pump company...? ;-))
Bye,
Marianne Vanderveen IBCLC, Netherlands (and wondering about the
(non-existing?) storage capacity in the milk ducts and the sticking of milk fat to the duct walls, apparently denied by the same research(er) and even more wondering about this after yesterday's interesting story about the trick to get strings of milk out, strings that certainly come from the ducts and not from the alveoli, I would reckon...)

I must have missed something. I did not know that vacuum was a prerequisit
for full milkejection. If so, how come moms can easily and often even better
hand-express than pump?
Warmly,
Gonneke, IBCLC in PP, LClecturer, wondering in southern Netherlands

If you believe the research on let-down which shows that if there is not
adequate vacuum on the nipple, when the milk lets down, it 'backs up" into
less full areas and is less available on the next let-down,
