Baby names dilema

Britni
Hey ladies, so my husband and I are having a baby girl in April 2016!!!! Yay so excited!!!! So we are still deciding on a name.... He wants to name her Christina, the name is very beautiful, but he has a son (my step-son) name is Christian. I think that's too close for comfort, what do you all think??? By the way I really love the name Naomi and I'm praying my husband will like it to!!!
