Naming baby

I can't decide on a name. I don't know why it's so difficult. We named my son right away, no problem. This baby is a girl, and I keep saying when I see her I'll name her but I'm afraid of being indecisive in the hospital and just naming her to give her a name...... Sounds dumb, I know. Lol we like these 3 names......
