I need some advice and support! Backstory: My FH insisted we wait to get engaged until after his brother's wedding, so as not to steal their spotlight during their engagement etc. That wasn't a huge deal to me, our engagement came at a good time. However, we just found out his brother and his wife are having a baby - which is of course SO EXCITING. The bad news, their due date is the DAY BEFORE OUR WEDDING. His brother is of course his best man, and his wife is one of my bridesmaids. They lost their dad as teenagers and I know it is EXTREMELY important for my FH to have his brother there. I've already told my bridesmaid I completely understand if she doesn't want to be in the wedding party, and I'm equally supportive if she does - we will make it work! I'm freaking out though, that the baby will come the day before or the night before the wedding, and his best man won't be there. I know there is a good chance the baby could come before, or after, the wedding, but I can't stop the nagging feeling. I also am worried the pregnancy (a first for his mom's side of the family) could steal some of our spotlight. I feel terrible for feeling that way because I am so excited for them to become parents. Moving our date is out of the question as we've already got tons of the planning in motion and we've already waited until their entire engagement AND wedding was past to get engaged ourselves.
How can I continue to plan and put the worry away? What kind of backup plans should we come up with? How do I accept the fact that my wedding may not go the way I plan?
