My power went out when Irma hit! :(

It went out around 10am, and by the time we got back at 8am the next morning, it was already back on, so I'm not sure what time it came back on. But we left the house that night at 8pm so it was some time in the night/early morning.

I had a ton of frozen breastmilk in the freezer. Before the hurricane hit, I did turn up the freezer higher a few days prior knowing that the power might go out. When we came back home, the breastmilk was still frozen! Just like it normally is! It wasn't even defrosted a bit! Is that breastmilk still good??? I would absolutely HATE to throw away all that milk and start over with storing if it hasn't gone bad!
