These girls have another sibling, so they are triplits! (or some other quantity other than 2)

[vvildcard]

My best idea is that there are in fact two mothers involved, one of which is the mother of the other (ie: grandmother). A daughter and her mother both give birth at the same time (didn't they make a movie about this? ... with Steve Martin, I think) and the grandmother is classified, in a more traditional sense, as the mother of both babies.

They were adopted, the adoptive mother has assumed the position of "mother" upon birth. It says "to the same mother" and not "from the same mother"

Twins - Back to the Logic Puzzles
Two girls are born to the same mother, on the same day, at the same time (Edit: of course, not both at once - one right after the other - you know what I mean ), in the same month and year and yet they're not twins. How can this be?

The two babies are two of a set of triplets.

Spoiler for .

the mother is a cat. cats can have multiple fathers for her litter. they are not twins, just half siblings.
i know this may be stretching the puzzle, but it says nothing about the mother being human......

It's possible for the mother to have had two eggs that were fertilized at the same time.

The two children were born on a leap year

[bwmeekin]

Well when we are still an egg, we have 20 X chromones until the egg is fertilized. Each sperm has the X(girl) or Y(boy) chromosone. So when the egg is fertilized, it's a 50/50 chance it will be boy or girl. But when two sperm fertlize the egg it creats twins so if the inherit different traits then they don't have to be twins

Not sure where you got this idea or where you got the number 20. An egg has one X chromosome, not 20. A sperm cell has either one X chromosome or one Y chromosome.

Yes, they do. Although twins occurring due to two different sperm fertilizing one egg is extremely rare, they are still twins.
