So I have a friend who just got a 3D/4D ultrasound through this new place in Orland Park called My Baby Bump 3D 4D Ultrasound. I wish I would have known about them when I was preggo, but at least I know about them for my second! The images were so clear - I swear the baby looks just like her husband!!! My friend took me with so I could see the whole process, and she even got to bring her grandma too! The lady that did the ultrasound's name was Mary - she was so nice. I am not sure how many technicians they have, but if you can get her, she's awesome.
Anyway, they're offering 10% off of any package if you mention this thread. Their website is www.mybabybump3d4dultrasound.com. Have fun!
