troubles pumping. help 😭

Holly • Engaged. Dog mom. FTM-to-be. due Dec 22.

ladies i need help. my milk is just now coming in . i have to pump , can't breast feed (long story short my baby was born 35+1 so not a good sucker at first.) I need to pump 1. to feed him & 2. because my boobs need it. my nipples smrun on the 24mm flange, but yet the 27mm is too large. these are both uncomfortable due to these reasons. .(
