Uhhhh, this kid man. He never cooperates with anything. I have to usually hold the monitor to check the heartbeat during my NST because he sinks into my back, or during ultrasounds he sits perfectly still only opening or closing his hands or grabbing his feet. He isnt even making breathing motions like they want him to be doing when they are watching him. Everything is fine otherwise he is just a jerk. But ya ask him if he still has a penis (my husband did) and he has zeros issues showing you that. With our first 3d scan he kept his feet by his face the whole time and with this one he kept his hands there. I guess I'm in for a long haul with him.
