I got pissed every time I heard that "Who is married?? Who has kids??" speech at the start of every phase- so much so that it went into my critiques. I've been married for 3 years and change now and had a kid during primary-I had 0 issues.
Well get over it. I am not one to say that you shouldn't get married during flight school, it all depends on the relationship, but there were always a few of the married guys that would pull the 'I have wife/kids' excuse for various things, especially duty, while I was in the training command and to hell with the rest of the studs. Like the 'I can't do any events before 0730 because I have to drop my kid off at daycare' at the RAG and other idiocy that colored my view of things a bit. Not sure how that one flew but the guy who had 5 kids, that's right 5 little rugrats by the age of 26, never complained or missed anything except for the birth of number 5.
Surprising or not it was never much of an issue in either of my fleet squadrons. Guys and gals who needed to do family stuff took care of it quietly and made sure they pulled their fair share. Everyone's experience is different but I had a lot less problems in the fleet than TRACOM with this sort of thing.
