will have a good look through you list later, phantom, am at work right now - but as for the bottles and the breast pump, I didn't use Medela bottles, we had Tommee Tippee Closer to Nature. I didn't express that much, just what I could, and I used to save what I had in the fridge till there was enough for a chunk of a feed and then used it to top him up after he'd had formula. (in a separate bottle). I actually only had one Medela bottle, which attached to the pump, and when I'd got all I could, I poured it into a small TT bottle and kept it in the fridge and washed the Medela bottle out.
if I was going to be expressing a lot more/exclusively, I guess I might use Medela bottles. but you certainly don't have to.
