Another question on storage - when you say the ice cube trays, is this the specific breastmilk ones? (or can you use normal ones). where do you buy them?

can the cubes of milk be stored in normal sandwich snaplock bags?

would you still put 100ml in a bag (or whatever for one feed) or can you put more in and just get blocks out as needed?

What sort of amounts would a 4 month old drink? I have just discovered my DS will drink EBM (DD would only spit it out).

Is washing bottles in the dishwasher ok? I know you don't need to, but DH put them in and i felt like i had to wash them again, but not sure why.
