This is where they check for the nose bone to be grown in (and it is!) and they measure the fold of the neck to check for Down Syndrome. Everything looked good.
We had 3 scans. Petri was being very stubborn... this really is our child and would not lay on its back. So we went in for the first.... got some cute shots and couldn't get the neck measured. Went around to walk for 10 minutes. Came back... same thing.
