Thanks girls. I think I'm just going to go with my gut and keep using it as long as it smells fine. I also figure that DS would probably be pretty quick to reject it if it didn't taste right.

MantaRay - Gosh I can just imagine how hard it would have been pulling the EBM out of the freezer and knowing that this amazing milk you made yourself is now going to waste!

Loula - I started expressing once DS was about 2-3 months I think. I did it because we knew that we wanted another baby fairly close in age and I was worried that I would have to wean well before I wanted to in order fall pregnant. We ended up going through IVF and I was still able to breastfeed through that which was great. It's actually now that I'm pregnant that things have gotten hard and my supply dropped dramamtically. And now in the last week or so I think the milk has turned to mainly colostrum and DS only gets a few mouthfuls, so I figured I might as well start pulling some of the EBM out of the freezer and giving him a sippy cup of it in the evening
