So my sister is pregnant and is due a week before my wedding.... which we did not find out until after we picked a date and set it up with the church. My parents (who are paying for a big chunk of the wedding) now would like me to change the date and move it back atleast a week. It would help them out a lot and that way my steo mom wouldn't have to choose between my sister (who will probably have complications with her birth) and myself. However I have already had my heart set on this date and began making arrangements around it. Should I change it for the sake of my parents?
