I have many bowls / pots different conservation and these are the most practical for lunch because they may contain at least 300 g of food. Other small pots have a handy screw cap but you can not put it as 200 g of food (eg Advent). Now, from 9 months, we go to over 200 g ... It should be handled with care if the bowls from the freezer because the cover, under the effect of cold, can break if they are dropped (and yes, I'm clumsy :)) The format "bowl" rather than high pot is also nicer because it looks like a plate.
