So I came across this blog post that featured a new study (2011) that showed unpasteurized breastmilk perfectly safe after being thawed and re-frozen!

That's so awesome, and I'm sure welcomed for us moms that have hated having to toss milk because of power outages or childcare providers not needing the thawed milk!

Here's the link to the study!
