I think I want to freeze my milk. I have a good amount in the fridge and it's going to start expiring by Monday. So I think it's best if I start freezing. & I'll probably breastfeed for a few more weeks. I need advice and to know more about freezing. It's good for 6 months? I read it's better to freeze 4oz at a time. After thawing, it must be used within 24 hrs? What's the best (fastest) way to thaw frozen milk? Any other advice and/or things to know? Tia!
