In-laws pregnancy announcement ideas (baby #2)

My in laws (husband’s parents & sister) will be visiting the weekend that I turn 12 weeks, I think it would be a great opportunity to tell them in person. Looking for ideas! I had two, but open to others!

1) Have our son wear his “Big Bro” shirt that we used to announce to my husband with a jacket over top & take his jacket off when we go to dinner to reveal his shirt

2) We go out for dinner, have someone take our photo & on 3, we say (my name)’s pregnant!

I think with either, we would also bring our ultrasound photo
