My sister’s due date is my wedding date.

Oh gosh ... that is tough. would changing the date even work for you though in terms of your vendors and venue and time?

Does she have to travel for the wedding? Is she in the wedding party? If she is local, she could potentially have her go bag at the ready, just in case.

Going into labor at the wedding would make it a memorial time, thats for sure.

It's definitely not crazy to change the date around her due date if that's what's important to you, which it seems to be. If you've booked multiple vendors, it probably won't be easy to coordinate all of them on another date but it's definitely doable. If this is what you'd like to do, I would contact all of your vendors ASAP and ask for the other dates they have available in the new time frame you're considering so you can compare from each vendor and settle on a new date. I hope it all works out!

That is definitely a tough one. My only suggestion, since your sister is so important, is to get married early (elopement) and have her there, and continue planning as you are if it will be too difficult to move the date.

Good luck with your decision.

I think this is a great suggestion!

That is tough, I think it depends what is more important to you! I'd want to be there for my sister when she gives birth. I'd contact all your venue first, see if they can just change the date. You might not lose any money. Then if the venue has a new date, I'd contact vendors and see if they can move your date as well. If they can't you can go from there. But I'd start with venue.

As for sending save the dates already, you can either send new save the dates, or a small announcement card that you are changing the date.

I would change it, personally. I just couldn't imagine not having my sister there

Agree with this 100% Also, first pregnancies (if this is her first child) can sometimes go over the due date. I would see if the venue has other dates at least a month and a half after the original date, as she probably wouldn't want to travel with a two week old (just an example ) best of luck! Keep us updated!
