Before bb was 8 months old, I made lots of vegetable and fruit puree and put it in an ice-cube tray in the freezer. The Western baby cookbooks say that this is fine....so long as you dont freeze the food for too long ie dont keep more than a month maximum. If you freeze, then you dont waste so much food because in the beginning bb does not eat so much and also it is a lot more convenient.
Of course, fresh is probably better but sometimes, it is OK for mummies to cheat a little
