I think you're competitive for the AD board, but definitely hit your 11 hour mark so you aren't leaving easy points off the table.
I'll throw some advise at you though as my buddy is a C17 driver married to an AD nurse... Make sure you both fully understand what you're signing up for, especially with a baby on the way. My bro just PCSd and his wife was unable to accompany him and it really is stressing their marriage, so definitely make sure you both talk those things through before taking the plunge. Double AD can be rough.
