Would you take kids to an ultrasound scan?

They're my stepchildren but they're really looking forward to their new sibling.

I'm just really scared something might have gone wrong since the last scan and they'd have to see their dead sibling inside of me?

They would be devastated, and ofcourse so would their dad and I be...

Our scans aren't done by techs but by the obgyn themselves always so they're obligated to tell if anything is wrong.
