Waiting a year to name a baby..?

Tina

I was on YouTube and saw this video pop up... what are your opinions on waiting a year to give a baby a name? The name on her birth certificate was “A”

Edit*** I don’t have anything against it and I have never heard of anyone else doing that until that video popped up.. I just found it to be something interesting and wanted to hear others opinions or see if anyone else has heard of someone doing it.
