I figure u/s is safe enough that if you really feel like you haven't bonded and this will help, you should go for it. Of course I've had a million (not this pregnancy) because of complications and my babies are healthy so I can't see any harm in them. Plus, the pictures are pretty neat. lol. Since I had to be in all the time during my last pregnancy, the tech flipped the 3d thing on and took a few pictures for us just because.
