I just wanted to get some input from people who have done a 3D ultrasound. There is a living social deal right now for one.The only thing is that it expires when I am just 25 weeks (I'm 9 weeks now). I know it's best to be between 28-32 weeks. Would you go for it? It's just $65 instead of the normal $140. I never did the 3d with my DD, but I really want to to take her so she can see the baby and get excited about becoming a big sister.
