The baby food doesn't just pop out of the ice cube trays like ice cubes do, probably because they don't freeze as hard, so they just flex with the tray. I suppose you could spray them with non-stick cooking spray, but I felt like that would defeat the purpose of all natural baby food. Oh well. Instead, I portioned several days worth into a freezer bag and have just defrosted that as I see fit.
New food of the week: Bananas!!! They were a hit. No surprise there.
