My in-laws call the baby by a pet name we never picked, and now he answers to it
We spent months choosing his name. My in-laws call him 'Chintu' and nothing else, and now he turns his head for Chintu faster than for his own name. My partner thinks it's harmless and sweet. I think we're going to end up with a 30 year old Chintu. Is this just what happens in every family, or did anyone manage to keep the real name in use?
