Happy Birthday, Leap Day Babies

I always wonder how people born on Feburary 29th celebrate their birthday. Do they do it only in leap year? Or every year on Feburary 28th or March 1st. I actually don't know anyone born on leap day so I have no one to ask. I have always thought that it is due to the fact that being born on leap day is small. Well according to the Honor Society of Leap Year Day Babies, the chance is 1 in 1461. Then I heard a report on the news radio that when a leap baby was born, the doctor asked the mother if she would like to put on the birth certificate either Feburary 28th or March 1st as the birthday. I wonder how many mother would do just that.
