Life as an Army Mom

As my son gets all settled at his new duty station the worry sets in for this mom. He was told that they are due to deploy next Spring/Summer. How does one truly prepare for their child to be in a warzone? I have kept myself busy with my others sons and my granddaughter who are all living with me. Total chaos in my house at all times but I love hearing their laughter so I wouldnt change that for the world.
