Telling parents!🤗

My husband and I are having my parents over for supper tomorrow and are planning to tell them the exciting news, I just don’t know how to tell them! We have a onesie that says hi grandma and grandpa but I don’t really want them to “open a gift”. Not sure if we should have a little set up on the table for when they first come?? Or just nonchalantly hand them a folded onesie or something?? Haha. Any ideas!? ❤️
