Siblings Sharing Birthdays

An Ohio couple has three children who were all born on the same day of the year. Their two boys were born in 2003 and 2006 on October 2. They just had a girl also born October 2. I have two cousins (same immediate family) that are similar, but aparantly the odds of having three children all with the same birth day are about 7.5 in 1 million.
