Re: A few questions...
- It's best to use frozen milk 3-4 months from the time of freezing. The sooner you use it, the better. Having said that, I've used frozen milk up to 6 months old because I had store way too much.

I would just smell and taste it to make sure that it is good.
- My mother, husband, and I just poured the milk out of the corner of the bag, and it never made a mess.
- I've never had thrush so I'm not the best person to answer this, but I would probably toss it just to be safe, particularly if you have a pretty substantial stash. But again, others here will probably have more informed input than me on this one.
