Okay, so I've been using these WeeSprout containers for about 3 months now and they're seriously a lifesaver. At first I was skeptical about plastic containers, but these are THICK - like, 'survived being dropped by my toddler' thick.
The leakproof claim is no joke! I've tossed these in diaper bags, thrown them in the freezer, even accidentally left one sideways in the fridge overnight - zero spills. The twist lids are way better than those snap-on types that always pop open.
Love that they nest together when empty (saves so much cabinet space) and the smooth interior means no food gunk gets stuck in corners. Dishwasher cleaning is a breeze - comes out looking brand new every time.
Pro tip: The matte colored ones apparently have lid issues according to other reviews, so stick with the full color versions. I got the variety pack and can confirm the solid color ones work perfectly.
Using them for way more than baby food now - salad dressings, snack portions, even freezing coffee cubes. Worth every penny!
