Most moms have an ultrasound at some point for dates, check healthy development or if there are any concerns during their pregnancy. Recently 3D ultrasounds have become more and more popular for new parents to get a realistic 3D image of their unborn baby. The technology and photos are quite spectacular and YouTube has many you can view if you are interested. Some are promotions of the 3D company, others are proud parents wanting to show the world their baby. It can be a bonding experience for mom and dad and a treasured keepsake but do consider some pros and cons and follow the links for some important information.
PROS
"Recently, 4-D or dynamic 3-D scanners are in the market and the attraction of being able to look at the face and movements of your baby before birth was also enthusiastically reported in parenting and health magazines. This is thought to have an important catalytic effect for mothers to bond to their babies before birth. What are known as 're-assurance scans' and the rather misnamed 'entertainment scans' have quickly become popular." (http://www.ob-ultrasound.net/).
CONS
"...possible growth retardation, dyslexia, and delayed speech development... a higher rate of left-handedness among boys exposed to neonatal ultrasound has been observed in at least three separate studies. (http://www.askquestions.org/articles/ultrasound/).
