And it did. Shaneka Hinton of Orlando, Florida, was born on Leap Day in 1988. Yesterday, she turned 24, although it was only her sixth birthday. Hinton spent the day in the maternity ward as she gave birth to Christina Raynette Clemente, yet another Leap Day baby! And what's more -Hinton's son was born on the Fourth of July. Now Hinton and her daughter will be able to celebrate their birthdays together -once every four years. Link

With those numbers, it would be phenomenally unusual if NONE of them shared a leapday birthday with a parent.
They calculated these odds just for the mother. That's arbitrary. They also figured in the odds of a mother already being a leap baby, which, of course, has already passed and has no bearing (!) on whether she will give birth on leapday.
Also, most parents have more than one kid. So they get multiple shots at this.
The 2M:1 odds are actually the odds against any mother you meet on the street sharing a leapday birthday with their first child.
