Simplify the prepwork for baby's meals with our silicone freezer tray that's perfect for storing food and milk for littles. The nine cups each hold 1.5 oz (4.5 mL) and feature interior ounce and milliliter markings to take the guesswork out of measuring. Frozen items pop out of the silicone base with ease, and the clip-on lid made from BPA-free plastic keeps your food secure and your freezer mess-free.
