My husband will also be deploying a few months after the baby is born so i know exactly how you are feeling. This is my first preganancy so I have no idea how I'm going to handle doing it alone as we do not have family around us. Yes, financially its great and I do understand and support what he has to do since I am a service member as well and have deployed myself, but I'm not quite prepared yet to deal with it alone with a newborn. I'll figure that out after I make it through childbirth!
At this point, I am really trying not to think about it too much because it is upsetting and I don't want to stress myself out. I want to enjoy this pregnancy experience and I do feel comforted by the fact that I will have our new baby with me as opposed to waiting out the deployment alone.
