Is it selfish to have my baby shower a week before my sisters ?

I'm due June 10th , my mother and sister in law want to plan it for April 9th, my sisters is April 16th. Should I tell them to plan it a little later or just keep the 9th? My first child so idk what to do! This is my sister 3rd child, she had a boy, and now two girls. Idk if it's selfish to have it a week before. My family is the type that won't show up to another one if they have already gone to one. This is my first baby, so I kinda want them all to be there and not be burnt out on baby showers. I just don't want to step on anyone's toes.
