Re: Need to double milk supply
You can't pump too much when trying to build supply, unless of course pumping is painful, in which case you need to tweak something in your set-up (pumping speed, shield size).
I strongly suggest getting a hospital-grade pump and using it all. the. time. It should give you an order of magnitude better results than either the manual pump or the Purely Yours. FTR, I used a Purely Yours and I consider it to be a good pump for a mom with an established supply who needs to pump 1-3 times per day, max. It is not a good pump for a mom who needs to increase supply. It just does not have the power. Particularly if it is used- and you say you got it from a friend, so if she used it first believe me when I say the motor will not have the power you want!
