One Step Ahead Baby - Jumbo Baby Cubes
This is a great little set of freezable baby cube molds for when you first start giving your baby solids. I would puree fruits and vegetables in the blender, and then freeze them. Then you can sit one or two of the cubes out so they de-thaw naturally and you don't have to worry about getting the temperature right in the microwave.
These can be used from breast milk to toddler snacks. Freezer, microwave and dishwasher safe. Reusable and convenient!
