Help me announce!

I found out a week ago that we are expecting! I've not told anyone! I have two healthy happy boys but have also had 4 miscarriages. During all these I've not really been able to tell anyone in person (especially my mom)... however my entire family will be together on the 27th for the first in 6 years since my parents split. I have a vague idea of how to tell them but am also at a loss. I have a onsie that says plot twist and one that says player 3 ready to enter the game. I have taped them to the inside lid of two different gift boxes. I don't know wjat else to do... who should open them. If I should hide them under tissue paper a little bettet.... help!!
