Okay, so I was skeptical at first because I've tried SO many baby food storage containers that promise to be leakproof but...aren't. These WeeSprout ones? LEGIT.
The 4oz size is PERFECT for baby portions - not too big, not too small. I make big batches of sweet potato, apple, and carrot purees on Sundays and these containers keep everything fresh in the fridge all week.
BEST FEATURE: The lids actually stay on! I've thrown these in my diaper bag sideways and never had leaks. Even after freezing breast milk in them, they don't get that weird freezer burn taste like other containers.
Cleaning is a breeze - no weird corners for food to hide in. Just pop them in the dishwasher (top rack) and they come out looking brand new. Though fair warning - the matte colored ones seem to have slightly worse lids than the regular ones based on other reviews.
Bonus: They're great for toddler snacks now that my little one is older! Cheerios, chopped fruit, yogurt drops - all stay fresh. Definitely recommend getting the full color set rather than matte if you can!
