We’ve both made and frozen baby food for our children. That is why we were delighted to find Munchkin Fresh Food Freezer Cups. The cups come in a stackable 4-pack tray that can be clipped to another 4-pack set. The stacking feature is great for anyone who has tried to store mismatched baby food containers in the freezer. The containers are made of silicone, so they are both freezer and microwave friendly, and the flexibility allows you to pop out the contents. The lids, which come in pink, blue or green, seal very securely to prevent spilling when packed to travel. Each cup holds 2 ounce, and markings on the side in ounces, milliliters and teaspoons are helpful for spooning out the appropriate serving size. A great product for new moms.
