Bringing kids to ultrasound appt?

Au

My girls are 7 and 9 and they’d really like to see baby girl at my ultrasound tomorrow. The ultrasound tech room is pretty small, there’s a little bench my husband sits on beside the table I lay on, do you think they would have a problem if I brought my kids in to the appointment also? I figured one kid would be fine, is two pushing it?

Edit: obviously I wound never just bring one kid lol. I was just saying I was worried two might be pushing it.
