My sister was in a similar situation with her DS. She was in England when he was born, everyone was back here. So my mum booked flights for 1 week after he due date to stay for one week and her IL's book two weeks later for one week. That way everyone got to see her DS when he was little but my sister and her DH got time to them selves as well.

Do it your way. It is your baby, your home and your family. GL
