I love the whole concept behind Kinderville's storage jars.
They provide a one-stop solution for not only being able to store your children's foods and snacks, but also do so in a bacteria-resistant, BPA, Phthalate and Lead-free way, unlike your typical plastic containers. Not only that, but you can use them in the dishwasher, refrigerator, freezer AND microwave ~ talk about some great versatility! They also are made to stack together and are perfect for storing baby food, snacks or leftovers, and of course, being able to warm it all up in the same container without harming your little ones. They are available in 2 sizes, as well - the little bites (set of 4 for $19.99) and the bigger bites (set of 2 for $16.99).
They also have toxin-free freezer trays (set of 2 for $18.99) with 2 oz. serving sized cavities, which would be perfect for storing homemade baby food.
And these I would also love to have for making toddler yogurt pops ~ their adorable popsicle molds ($16.99 for set of 4).
