This is probably a really dumb question but I'm a FTM 😩. Can I use any brand of bags to store my breastmilk? Or does it have to be the same brand bag as my breast pump? Asking because I'll be getting a free pump through my insurance from the hospital I'll be delivering at. I'll be receiving a Spectra pump. I'm looking online though and I'm not finding much for spectra brand storage bags? I found an off brand called Mommy's Precious that seems to have great reviews and super affordable, but I don't want to put them on my registry or buy them myself if I can't use them. So many questions with a new baby on the way! 😱
