Hello, do you use ice cube tray specially designed for baby food? Any good brand to recommend?

You can use this baby food tray. Many of the mummies are using this. http://www.pupsikstudio.com/oxo-tot-baby-food-freezer-tray.html There are some mummies using the ice cube tray with lids from daiso. I am using this too. It can be easily popped out.
