I had never heard of the nub/ skull theory until I joined MN and have been fascinated by the various prediction posts.
So just for fun I thought I would put up the pictures from both my 12 week and 20 to see what you guys predict. I had a go myself but was pretty useless.
I am currently 22 weeks and have been told what sex they think the baby looks like (I'm debating whether to get a private scan done to confirm this but that story is for another thread).
Here goes, let me have your thoughts?
