My father-in-law doesn't like the baby's nickname but insists on using it. What should I do?

Is it wrong to call the baby? Isn't he a baby? Your father-in-law is ill. I don't care. Their children make their own decisions, and they can follow them all their lives. Before she died, her mother-in-law said she wanted to read a dictionary. I said she should have someone look at the horoscope or something. Children are like this now. It's for their own good anyway. What's the nickname again? I can't say. Just a good name. No matter what the nickname is, it is called at home. I have many nicknames myself. Whoever calls me outside is my parents. It's no use since your father-in-law doesn't want you to call him baby, you can call him by his first name, which is always right.
