Do you think that a baby can show her/his personality from the womb?

The reason I ask is because I believe my daughter has an attitude, lol. I am high risk so I get a sonogram everytime I see my doc. He usually does a 3D on me so I get to see her features and things like that and she is usually not shy at all. My last appointment, my mother went with me so I was really excited about her seeing the 3D image. Well, my daughter wasn't being friendly at all! For one, she had her back toward us and when she finally moved she flipped us off, literally, lol. The doctor was so amazed he even kept a picture for himself. Then when they went to do the 3D on her face, she hid her face with her arms. She would not let them get a good look at her face at all but had her legs wide open, lol. Do you think she sensed she was being watched? Do you think it was becuase my mother was there? Most of the 3D images I have she is frowning, lol. Do you think she is showing her personality already?
