My mom told me yesterday she microwaved my brothers and my bottles when we were babies. I'm a FTM and could never imagine doing that. It's not safe! She was like "yeah with a screaming baby and no time to boil water, you just microwave it. It'll be fine. Shake it up and test it on your arm" I'm honestly afraid to let her watch my baby for more than one reason but this scares me. How did you heat up bottles?
