I'm 26 weeks pregnant and already making a lot of colostrum. I've started pumping once every couple of days because my breasts get full and start leaking a lot at night or they get painful, especially my right breast. I usually get about an ounce out at a time when I pump. So far, I haven't been freezing it, I've just been pouring it out. 
Should I start freezing it? If so, can I freeze an ounce, then the next time I pump, add the new ounce to the bag with the frozen ounce? Or does each pumping session need it's own container? I'll be pumping and freezing once the baby is here too because I'll need to return to work around 6 weeks PP and will need a good supply built up. Can I mix the frozen colostrum with the expressed breastmilk in bottles for the baby when she's older? What would you do with a frozen stash of colostrum?
Oh and I will stop pumping if it starts causing contractions.
