Military Mamas

Liz
I'm seeking some advice from military moms. Before my beautiful bundle of joy, I was set to ship off to Parris Island and become a United States Marine. I'm still on that path, but rather than active duty I will be a reservist. My questions for guys are these:
How did you cope being gone?
How was your relationship with your child once you returned?
If you went on a deployment, how was that?
How was your support system?
How did the custody situation work? (Keep in mind I am a single mother)
It's been suggested to me to simply wait and join later, but as it would turn out that is not an option for me.
Thank you in advance, ladies!
