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

You can consider Qubies freezing tray. I am using it for my baby. It is very convenient to use and saves space in the freezer. Here is a short video on how you use the product: http://www.newbabysingapore.com/feeding/solid-feeding/qubies-freezing-tray-detail.html#.VyDNR8vmhnE You can get it from their website too. Currently there is $5 off from $32.90.
