ultrasound 3D...???

[jude3602]

Does anyone know if a 3D ultrasound is a mirror image or exact image? I'm trying to figure out if my baby girl is left handed (like her daddy) it a righty like me :-) The consensus is that they are handed with whatever hand they are sucking their thumb on...

Anyone know?

Lol this is a funny topic. How can one possibly make out anything with those horrible ultrasound images.  Let alone determine which hand the baby favors based on a 3D image?

I'm not sure ull be able to tell based on a 3d ultrasound if ur baby will favor one hand or another.  I think that will be determined when baby is out.  I know that I started noticing my son was a lefty at around 9mos of age when he would hold his baby bottle with his left.  Then as he started walking and playing with balls, he would throw with his left and even kick with his left.  I'm proud to say he's a true lefty and I'm wondering if this next one will be lefty as well, although both dad and I are righties left handedness runs in my family.

I get what you are saying, as I too have studied and teach prenatal development. I'm not trying to play agame of who knows more.than whom, but with your background you know you can't make that.assumption about one visit. I get ultrasounds quite often due to my having twins and have seen them suck both.thumbs. like I said, they do show preference in the womb, but you couldn't use one ultrasound to prove.that's their preference as they may use both hands interchangeably for years.
just yesterday my parents called and.asked if my.almost two year old.was a.lefty because he favored that hand a lot that day and his older brother is. however, my youngest uses his right.hand to write and eat, but that.day had.switched for whatever reason. not saying it couldn't be correct, but it wouldn't be proven by one ultrasound. any scientist would.tell you that is too small a sample to provide proof

Camerinj,
As a PhD in psychology I disagree that there isn't any evidence to backup my easier statement. My course work in developmental psychology is extensive. However, my knowledge of ultrasound is limited.

I can't answer that question, but I can tell you that while babies can form a preference that early, many will still use their hands interchangeably for quite some time after birth. this will just be one of those fun things to joke about, but is not based in scientific fact

I had a 3D on Friday & the tech said it's the opposite of what you see on the screen.

I don't know, but I think it depends on the techniques of the US tech. You would have had to ask her when you were in the office, because they get different shots from different angles.
