I got this from the hollyoaks Forum
So what you think
HOW unrealistic.
You cannot just decide to change the baby's name moments before the christening. Births have to registered within a certain number of weeks after the birth and of course at this time the name is confirmed and registered by means of a birth certificate. The name Antonia would have already been registered and the christening is not a legal ceremony, it is a religious formality and therefore the name couldn't have been changed this way.
Idiots.
