I swear I'm not stalking you, your posts keep popping up in 'new posts' LOL!!!

MIL is on the ball, lots of 50ml is a good amount to store (or even 30 ml). The cubes can be a really good way of doing this. Once the milk has frozen in them you can transfer the blocks/sticks into a zip lock bag. Personally I think that although really good, the EBM-specific storage bags are a really exxy way of doing it, and it encourages you to store larger amounts. Which can be really wasteful! Which can be heartbreaking after you've spent much time expressing the milk in the first place (as most mothers do). I LOVED using the specimen jars when DS2 was in SCN, but unfortunately that's not a cheap option (unless you're getting them for free from SCN ).

Have you had a look for ice cube trays that are BPA free? There are specific ones for BM available.........check out the Mother's Direct website (don't forget you get a 10% discount there LOL).
