What If You Have No Other Options?

Sometimes life happens and you don't have access to anything other than a microwave. This is the kind of event that can arise when you're out at a restaurant.

If you find yourself in this situation, you still have options. Most likely, you're going to need to enlist the help of your server. 

To heat the milk, you need hot water. Ask your server to heat a bowl of water in the microwave to a warm (not hot) temperature and bring it out to you. Once you've checked that the temperature is suitable, place the sealed bottle of breast milk in the water until it's warm enough. 

This is usually a pretty easy task for both you and your server. If the restaurant is really busy, a few extra bucks on the tip will tell your server that you appreciate the help.
