So we just found out we are expecting this past Monday after 2 miscarriages. My sister in law is also pregnant, due 5 weeks before me. I know she's going to be upset and feel like I'm stealing her thunder. Also, we want to announce early in case something happens again so we have the support of our families. What is the best way to tell my in-laws they are gonna be grandparents twice? And how do I tell/handle my sister-in-law?
