wow your not to smart are ya? babys are not obese when they are born *rolls eyes*
yes but she is still in my belly right now and ya cant see though my belly lol so they us a 3d ultrasound (which use sound waves to make a pic) most commonly women only have a 2D ultrasound-which is the flat black and white image that most time people dont know what they are looking at
you cant just see a baby in the belly they use different sound waves to view the baby while still in the womb..which then give you a 2D image.. and or a 3D image .... 4D is whats gives the 3D movement
