This is a fairly robust, some pity pot is damaged with the passage from the freezer to microwave or babycook, it feels like cracks, but it never completely broken. I would allow to tell you to buy directly the 500 ml 300ml since become just as quickly at 18 months children eat a ration of 260gr per meal, so the mixture exceeds the pot! After smaller as 150 ml is good for dessert as compote ....
