Just out of curiousity..

I go in for my 36 week ultrasound (eeeek so close!) tomorrow morning. I have been offered a discounted price for 4D pictures (or 3D.. I forgot). Anyway, I was just wondering if it was worth it from people who have already gotten them? Does it actually look like your baby? I know I might sound dumb but I don't want to spend the money if it's not worth it :) thanks ladies!!
