My little girl was being very stubborn. Instead of 30 minutes, it took us an hour to get her to move her hand, arm and sometimes her foot from in front of her face! I had to eat candy, ice and switch sides several times! But after all that...I had a nice experience! The ultrasound tech was super sweet and patient! Think I may go back 😍😛 she looks good and is measuring 3lbs13oz
