Kate, I realise that this is the purpose of the scans. Having a look at DD was an added bonus for us . We were there for a dating scan. It wasn't an NT scan and was not backed up with the usual blood tests.

There are additional ultrasounds you can get though if you just want to have a look at your baby. I won't begrudge any woman who wants to have a look at their bubba! It is a great stress relief and a wonderful way to bond.
However, if she examined the NT, the NT scan has been done, even though that wasn't the purpose of you having the scan. The blood test in conjunction with the NT scan is known as the first trimester screen, (which you didn't have) but by default you ended up having the NT scan.
