I am 24 weeks pregnant. Dh and his parents want me to have a 4D scan because his brothers wife had one with a video as well which they said was brilliant and helped with bonding 
I have researched it and don't feel comfortable having one because:
There is no evidence that they are safe, despite what the companys website says.
I was told by my midwife that you shouldn't have too many scans.
I can bond with my LO quite well without a 4D scan thanks.
They think I'm being selfish. Am I?
