for hypoallergenic, NAN Optipro HW. But mommy, breastmilk is still the best for baby. Maybe kaya masakit yung pumping sesh mo is due to incorrect flange size. You may join Magic 8 mommies group sa fb. Maraming tips and tricks po dun on how to build milk stash. Also, what are the reasons why masakit ang pagpupump mo. I have a same case po, may history ng allergy and I dont wanna take risk na ipag formula si LO if may ganung hx ako kasi trial and error din po ang formula feeding. There was a time din na akala ko okay lang to eat seafoods (im allergic to it), then napansin ko na nagkaka dry patches si baby sa tenga and face. My pedia said it was due to my food consumption. So be also cautious with that po. I hope nakatulong. Stay safe mommy!
