My child’s name was not chosen well, but my husband thinks it’s okay. I really regret my decision and don’t know how to change it.

Since you have chosen it, let it be. The name is just a code name. Even if you feel bad, you can still record your mood at that time. Think about it, many years later, your child will ask you, why did your mother give me the name? With this name, you can tell him this story. He said that his mother still regretted it at that time, and that her mother was very cute.
