Too much milk!

I not complaining because I know many women would be so happy to produce enough milk, never mind more then they need.

I'm home for 18 months on maternity leave so I primarily breastfeed but bring bottles when I go out or leave them with husband if I go out without baby.

I pump 1 6 ounce bottle each morning but now my freezer is over flowing and I dont know what to do with it.

I dont just want to dump it but to donate it I have to really go out my my way and I dont want to feel committed to pumping because of it.

What do I do? Start dumping the old frozen stuff and replacing it with fresh?
