I know this sounds incredibly silly but I am really panicking about this today. I had a 3D scan of my baby at 18 weeks to find out the sex and a couple of the pictures have worried me. Organs etc all looked fine, but the bit between his skull and nose seemed a bit odd. I keep reading everywhere that baby's develop a button nose which becomes more defined, but our little one the skull seemed to go straight down into a long nose with no real bridge there. Could it be that this will change or could it be some indication of something being wrong? If it is just a big nose then that doesn't matter but I'm really worrying something is wrong. My 20 week scan is next week but I'm guessing a 2D won't look into this?
