I am going to a place called Early View this Saturday and they don't need a referal. Here is the website: Early View, Ultrasound 4D Sydney Australia - Baby Ultrasound Imaging
They have a lovely comforting atmosphere and that is what we are after. Especially after our 19 week scan which I walked out of nearly crying cause the sonographer was so rude. 4D is not cheap nor can you claim it back, but I figured its a once in a life time opportunity, so why not!
