Naming and gender pre-birth; WHY?!!!

Julie • Feeling future focussed and even more determined to make my baby dreams become a reality; and now I am in a relationship
Some mums to be have the name worked out and the gender at 20 weeks gestation. 
I know that I would want to meet my baby first and look into their eyes, their face and characteristics before naming them, just to make sure it really is a match and the name suits😉
The finding out the gender topic at 18-20 week fetal anatomy scan, hmm controversial isn't it.?
I am going to wait to see what I get and what a surprise it will certainly be.
What are your decisions?
