Qubies are ice cube trays that make 30ml-sized portions, perfect for feeding babies, but also for anyone who needs to freeze foods in small portions. Regular ice-cube trays divide up into portions that are too small for foods. The unique thing about Qubies is also that the dividers are in the lid.
Then again, Qubies aren’t cheap at AU$16.95 each (excluding postage). The cheaper, but less elegant and more space-consuming option would be use a bunch of stackable Lock & Lock E-Z Lock containers, which is what I have been doing so far. However, the smallest E-Z Lock is 190ml, which is sometimes be too big. Canton Pixie has mentioned in the comments on this blog her method of using disposable (but washable & reusable) plastic sauce or pudding containers from SKP to freeze baby food.
