Congratulation
yes
It does not really matter whether it is the groom or bride's parents who call. In many cases the groom's parents call, but, etiquette does not dictate this.
To the parents you can say something along the lines of, "Congratulations on bringing this new beautiful life into this world!" If it's something for the baby you can say, "Welcome to this world little one!"
It is better to say "congratulations" when congratulating someone because it is the correct plural form. Saying "congratulation" is grammatically incorrect in this context.
