Twin info I forgot to mention

For those of you who like details...

The twins are each in their own amniotic sac, and they each have their own placenta. This means that it is more likely that they are fraternal twins (not identical). However, it is still possible that the twins could be identical. If we find out that Baby B is a boy, then they are fraternal, but if Baby B is a girl, they could be either.

One of the first questions that people have been asking is whether twins run in our family. As far as we know, there is only one set of twins within the generations of our family that are living today (Aaron's Dad's cousins - Pam and Penny). Apparently, each of us also has a great-grandmother who had a twin pregnancy, but neither one carried the twins to term. An increased likelihood for fraternal twins is genetically linked to the mother's there is only one instance of a twin conception that we know of that is relevant to my genes - and it is a number of generations back. (From what I've read so far, it sounds like genetics are not thought to influence the likelihood of identical twins.)
