That's pretty awesome! And it's more awesome that your DH is supportive of this. I know my parents wouldn't move back here, not even for my kids. I definitely don't want to move back to India, not until Mira is done with her education, so we'll travel back and forth about as often as is practical.
I have already started planning on having my parents live with me when they get older if they want to. I will even move back home to my hometown if necessary, like they don't want to leave or something.
