she had her baby, then delivered someone else's as an ob-gyn

You don't much about giving birth do you?

so... you are coming up with these yourself, aren't you? ¬¬

They were two of a set of triplets
(or quadruplets,ect)

The lady had triplets! Number one!!!!!!

if you look at two individuals in a set of triplets or quadruplets then I'm pretty sure those two are still twins in comparison to each other.

The two sons had different mothers. Natural Birth is what the woman named her dog.

Samurai Pal you are absolutely right! LOL!
And anyway, do they have to be twins if they are born at the same time (from the same mother of course)?

This one is kinda old.

she gave birth to two babies at the same time! they must have been really tiny, or it must have been sore as hell!

The last one is my personal favourite.

Samurai Pal is frikken hilarius, talk about u have to have an imagination LAWLS

It would be better for the riddle if the children were siamese. But would it still be a case of natural birth?

i have another answer. .
two sons could be the name of the child.

all the other stuff is misleading.

that answer wouldnt work because it would make the sentence incorrect. "Two sons WERE"

couldn't the woman be the midwife ??

although very rare, a mother can give birth to more than one child and have them not be twins. look it up it has happened.

I guessed she was a doctor who delivered two different babies.

derek - I don't think that's true. You can have fraternal twins, but if they're conceived at the same time and birthed at the same time then they're twins, no matter what.
