Twins

I was so simple before.
If you have two genetically identical children at the same time, they’re called twins.
But if you take one embryo and implant it in another woman, are they still twins?
What if you take one egg, replicate it a few times, and implant them all together?
Twins? Triplets? Quadruplets?
And what if you don’t implant them all at once? Maybe wait a year or two between pregnancies?
Are they now clones?
It’s so confusing. Makes it hard to buy just the right card, too.
Are you my brother?
Are you my mother?
Are you… me?
