Fill a bowl or something with hot water (I use a Pyrex 2 cup liquid measuring cup) and put the bottle in for a few minutes. Test a few drops on the inside of your wrist. Done!
We did our first bottle today to test how LO would react and get me some relief from nighttime cluster feeding. I have the Medela system so I had DH heat half of a coffee cup of water in the microwave for 2 minutes and then sat the storage bottle in there for a few. It heated up perfect and it was quick and easy! I didn't want to wait for the stove when baby is upset in the middle of the night so I'm glad it worked.
