I'm new to pumping, and so far all I've done is put a couple of bottles in the fridge. So I have questions about milk storage bags:
- Are all brands about the same, or are there features on some brands that are useful?
- Would I pump into the bottles as usual, and then pour into the bags, or is there a way to pump directly into the bags?
- What else should I know? I'm not looking to build a huge freezer stash, just a little backup. DD is four weeks, and at the moment I'm replacing one nursing a day with a bottle, and the last two days she's eaten 5 oz at that feeding and I've pumped 7. I have the Medela pump in style advanced.

Thank you!
