May 8, 2008 Qubies ice-cube tray is unique because it has the divider on the lid. Instead of trying to pour baby goop into a standard ice-cube tray, you simply fill the container, press on the lid and pop it in the freezer. A few hours later you will have a tray of 30 ml (about 1 fl. oz.) cubes of baby food ready for junior’s dinner.
