Gender ultrasound

For anyone who has had their gender ultrasound who did you bring to your appointment with you?

My husband of course will be there but I've also been thinking about bringing my parents. It's their very first grandchild and they are so excited and I believe it would be the best early Christmas gift I could give them. A chance to see their grandbaby for the first time.

Not sure if my doctors office will allow this but wanted to know if anyone else has brought a parent or both along with them?
