I know I'd LOL if I got that note. But I know some people get very emotional if someone else in the family announces a pregnancy while they're pregnant (there was a thread like 2 weeks ago about that), and the dibs thing is potentially a big "OOPS" moment.

Presuming they aren't cherished family names, the odds of them wanting the same names you want are sooooo low that it's probably no big deal.

(BTW care to share the two names???? I'm super curious!)
