There are fewer than 100 documented cases of "identical triplets plus one" in the United States, hospital officials said.
Two embryos were implanted into the mother, hospital spokesman Michael Schwartzberg said. One of them split, then split again, creating the identical triplets.
The boys were delivered by Caesarean section Jan. 29, their mother's 32nd birthday. Joshua Drew was born first, then Gavin Michael, Cody Benjamin and finally Logan Christopher, the non-identical one, Schwartzberg said.
The babies were treated at the hospital's neonatal intensive care unit, and all four have been home in Belcamp for about 2 1/2 weeks, Schwartzberg said.

Oh my gosh! Why would a woman want to have a child at age 62? Could you imagine the kid's childhood? Figure that the mom is probably near retirement already. And let's say the kid is 10 in fifth grade, and mom is 72. If the mom lives to see thier kid graduate highschool at 17, then she will be 79. How is that a good way to raise a child? Living in a retirement community. The kid would never last at school or anything becuase they are so used to everyone being 60 or more years older than them. How aweful!
Why do women try to defy the laws of aging? Trying to have a kid later and later in their life? It's not good for them. At 60, a woman's body isn't prepared to have a kid. Could you imagine how many complications there could be? Not to mention how scary it would be. I mean, come on! Have your kids in your 20's, 30's, and 40's. No later. If you have a kid at retirement age, then the kid's life will be traumatic. Think of the children!
