How to mix frozen breast milk?

Lindsey

I have stored and froze breastmilk in small amounts. Now that my daughter is getting older shes eatting more. I know to mix fresh breastmilk it needs to be chilled first then mixed together. Just wondering how to thaw (under warm water) two bags of breastmilk and combine them together?

Do i just thaw both bags and combine together?

Thanks
