Lansinoh milk bags

I am beyond frustrated. I’m 10 months postpartum and almost completely weaned. I did everything I was supposed to—nursed my baby, built up a freezer stash so he’d have breastmilk for his entire first year—and now I’m finding that so many of my Lansinoh bags are leaking at the bottom seam as they defrost. At first, I thought it was just one bad bag, but it’s happening more and more, and it makes me want to throw something at the wall. I was finally ready to have my body back, to lean on the stash I worked so hard to build, and to stop worrying about milk. Instead, I’m stuck playing Russian roulette every time I thaw a bag. Each of these bags is priceless.... I am so discouraged.
