Christmas announcement- yay or nay!

We plan to announce 3rd baby on Xmas to our families.

My in laws will just be them and my brother in law so we plan on giving my in laws a joint gift with a stocking and a card inside. I need help with wording and something more creative then what I have lol.

Note in/on stocking:

"You seem to be missing a stocking on your fireplace - baby #3!"

I feel like It can be more interesting than that?

My family's side will be a bigger group, aunts and uncles (the usual people we tell first)

I am a photographer and was thinking a group shot taking the photo with my remote and doing a practice shot and then the second photo saying "OK 1 2 3 everyone say Amy's pregnant!" (Not my name lol) and then snap a few photos. The only downside is my uncle from another state is coming out a few days after Xmas and he wouldn't be there for the group photo when we would all be together and I know he'd be bummed to miss out on that..

Any other ideas to announce at Xmas for a big group welcome. We will be skyping him and my aunt that day so if we can let everyone know at once without the photo I'm open to ideas, I just dunno other than "hey I'm pregnant again!"

I'm just stumped and seriously lacking something creative besides wearing a shirt or have someone open a gift. Wanted a bit different so no one would suspect it before it came out (referring to the large group, i want everyone to know at the same time, hence no gifts for that side. It's about 20 people so I figured the photo has everyone's attention at once.)

Thanks ❤️
