Is it okay to get engaged after a sibling?

I wouldn't worry about it. If they are going to get upset about an engagement (which people should be excited about) then that is on them. Not you two. Like the first comment, no one owns a set period of time.

Not at all! My friend got engaged and I got engaged the day after. We waited a week to announce because we wanted to personally tell everyone. People weren't less excited for them because we got engaged soon after.

Having more positive excitement is a good problem to have and I'd phrase it that way. You absolutely SHOULDN'T have to plan your proposal around other good news! I think a lot of people would love to have that kind of positivity in excess. That being said, they MAY start immediately panicking about logistics and timing with other weddings and babies being born. If they are planners, that's in their nature to jump to the practicalities.

I'd just be aware and head that off in advance- saying you both know there's a lot going on and you'll of course make every attempt to plan your wedding so it doesn't directly conflict with all these other exciting things (only say this is you are 100% comfortable and willing to set a date that avoids due dates of babies, etc.). This being said, be careful with the phrasing not to allow demands- you can agree to be reasonable without giving everyone a pass to veto your decisions! This is tricky and for some dynamics it may be a disaster, so use your judgment on this part

Girl, do your thing! You're engagement is about you, no one else. You don't get a monopoly exciting things from engagement to wedding... I am sure everyone will be thrilled for you.

That being said, I understand where you are coming from. FH proposed the week between my best friends destination wedding and her local reception. Her parents had been like parents to me and I spent an entire week with the rest of their families that went to Costa Rica. My girl also got really really REALLY drunk 2 nights before her wedding and ripped me a new a-hole about not doing enough for her and making everything about me which hurt more than I can express (she doesn't remember it and I don't want her to think anything but the best things about that week so I never brought it up). After she went off on me, and her FH, I was painfully hesitant about telling her when I saw her the day before her local reception... especially after being accused of making her wedding about me... but I also wasn't about to not enjoy being newly engaged and not wear my ring. I told her (her parents were there too) right away but prefaced it with it was not to be a part of conversation until after her reception. She basically laughed at me and said that wasn't going to happen (again, she didn't remember that night in Costa Rica).

What I am trying to say is, they will be happy for you, regardless of what is going on in their lives. And 2 engagements means someone who will 100% understand what you are going through every step of the way
