Can I microwave my breast milk to help warm it up faster?

Never. Not only does is ruin the milk, there can be hot spots in the milk that you can't feel and will burn the baby.

@ashtonndamon, I have a bottle warmer but it's at my house and I'm at my moms

I got a bottle warmer for like 15 that takes like 30-45 seconds.

I ran it under warm water

The microwave will kill all the important nutrients in the milk that make breast milk so good ! Warm water is the best way to do it

Warm water for 2 to 5 minutes is all you need. never microwave it by the time you change the diaper it is ready
