I think you guys are right. We should tell him. I think we will wait until we are home for Christmas so we can tell him in person. We will do it in a happy way.. "you are going to be an uncle!!" Hopefully he doesn't find out before then.
nbsp;Thanks for the responses!
If you're expecting him to maybe have mixed feelings about it, I would advise against telling him in an inperson, it's a big deal way. That puts pressure on him to show the appropriate amount of enthusiasm. And maybe he's not feeling very enthusiastic about anything right now. And for all anyone knows desire for babies could be part of his relationship woes.
It would be more tactful to tell him over email etc, so that he can process the information in his own way before being expected to say OMG GRATS! The same advice goes for notifying a friend or relative who hasn't been able to have children yet and struggles with infertility. If you put them on the spot, especially in front of other family members, you risk making their feelings a cause for guilt and or family drama. If you notify them by email etc, he can think about it and call you when he's ready to say OMG GRATS.
