DH and I are planning on telling our parents and siblings the news this weekend (at only 7 weeks), but he brought up a concern this morning. My step sister is getting married June 14th, and he doesn't want to steal her thunder. I can definitely see where he's coming from, and I think it's sweet that he's thinking about that. My thought is that it's over a month in advance, so it wouldn't really be stealing her thunder since we're not telling everyone. I kind of thought she would want to know, in case I can't participate in pre-wedding festivities. Also, if we waited until 12/13 weeks, it would be the weekend of the wedding, which would definitely steal her thunder.

I think DH has a valid point, but I'm just not sure how to handle the situation.
