How do I change the baby name in Glow Nurture?

How do I change the name of my baby in the app? When I first got the Glow nurture app I just listed the name as "J" because I didn't know what I was having, but I knew it would start with the letter J. I found out yesterday I am having a little girl and would like to change the name I have listed in the app but I can't seem to find where to do it.
