Husband just got deployment orders...

Im so upset right now. My husband just found out that he will be getting deployed right after Christmas this year. My due date is November 6th and our baby girl wont even be 2 months old before her daddy disappears for 6 months. It is our first baby and she was planned and now this throws a wrench into everything. Im so worried they wont bond in the time he is still home and she wont know him from a stranger when he comes home. On top of that, i am a full time social worker and wont have even returned to work by the time he leaves.... i dont know how any of this will get better. :(
