Christmas announcement to grandparents

Ca

I just found out this morning that I’m pregnant and I’ve been day dreaming all day about it.

I have my first appointment next week to confirm and then my first ultrasound in a month. I’d love to tell our parents on Christmas since we will be seeing both sets to open gifts. What kind of gift should I give them? I’d love for it to be a keepsake. Maybe an ornament that says “you’re gonna be grandparents!” Or something? When I say it out loud it seems stupid. What do you think?
