I exclusively pump n get only 2 ounces from each pump m 8 weeks postpartum I'm thinking of now buying a hospital grade pump as it's Black Friday and there is talwaar 25% off I mean still expensive I need to know if anyone has had any expiration switching to a hospital grade pump after 8 weeks and has that help increase supply. I don't want to spend 299 odd quod and then find out the outpouring is still the same
