5th Pregnancy Announcements?

Hi everyone, I'm officially a week late, I took 3 tests and got strong dark positives! Hoping and praying that this baby sticks after having 3 chemicals over the past 3 months. Anyway, this would be our 5th child! How do you announce a 5th?! Any ideas? I'd really like for the other children to be involved in the announcement. I found a couple cute ones that I liked on Pinterest, but the ages of my children are 7, 5, 2, and almost 1. And the 5 year old is ADHD, lol. So it's gonna be hard for the boys to sit still for too long. Just curious on ideas!
