What are you storing your BM in?
Also, if you start pumping more than 6oz from one side, you can get the 8-9oz bottles from Gerber and the threads fit on the horns for the medela pumps. I know it sounds like a lot, but I was actually getting up to 6oz on the left and 8oz on the right in one sitting when I was EPing for the twins. Those little 6oz bottles that come w/ the pump just weren't doing it. Plus, those colored Gerber bottles are super cheap, like $6 for 3 of them.
As Adrienne mentioned earlier, I just HUTH last week after pumping for the last year (what a free-ing feeling!)
I have a Medela PIS and used the bottles that came with it and then poured the milk into Lansinoh bags. I ordered the bags off Amazon because it was way cheaper than buying a single box from BRU or another store. In one year, I think I only had like two bags leak. I found them to be very sturdy and
I tried the bags but didn't like them. I ended up going out and buying more Madela bottles at Babies R US. I can't remember how much they were ( I had a gift card from my registry) so I didn't really pay attention. However they were probably cheaper than at a hospital. I pumped 3X a day sometimes more once I went back to work.
