Deployment

Well my biggest fear is/was that my husband would deploy around the birth of our son. We found out that he will be leaving as early as September. We are not sure exactly what date yet but our baby is due on September 24. I have noticed a strong presence of military wives on the site and I was wondering if anyone had any input or words of advise. How do I put on a strong face for my husband while being completely terrified to do this on my own? Any advice would be much appreciated!
