Telling the kids!! 😲😲😲

I don't know why, but I am so nervous! I have 3 step kids, ages 8, 11, 14. I am 5 months pregnant and we haven't told them yet. We decided tonight would be the night. So I bought little gift boxes and put ultrasounds in each box and we're going to give them to them as a early Christmas gift. The nerves are setting in... Goodness, gracious! ! Anyone else get nervous before telling their families? What was it like? How did you feel afterwards? Any stories would be appreciated to help ease the nerves. Please and thank you! !
