I don't like my child's name. Sophia is 5 months old, I chose the name for her myself, none of the relatives would be against it and everyone is happy.

But I can't call her by name, as if a barrier has been put up. It's really torture. I could not even imagine that this happens to parents. I really liked the name, and then hop, and something went wrong.

Now I try on other names for her, I cryevery day and quietly go crazy. Sonya is already baptized, it is impossible to change. Maybe someone had a similar problem? Please help me figure this out, I can't seem to do it anymore.
