re: Rotating work schedule- children

The only way this might be doable is if 1) she can quit her job or go part time, 2) she is very independent and secure in your relationship and 3) she has friends and family and a solid support system nearby. Even then, things can still go south. Missing holidays and birthdays sucks.

Just my .02.

ETA: You will also have to pick up the slack when you get home for 21 days. You have to be home, be attentive, and give her a break while you're there. When my husband's home, he handles all school drop offs/pick ups, sports practices, homework time, etc.
