After I released the book, a bunch of people asked me if it was even possible to get pregnant with Quaduplets and how that would even happen. In order to make the story believable, I had to do A LOT of research, including sitting in on birthing classes.
The easiest answer, according to Wikipedia:
QuadrupletsQuadruplets are much rarer than twins or triplets. As of 2007, there were approximately 3500 sets recorded worldwide. Quadruplet births are becoming increasingly common due to fertility treatments. There are around 70 sets of all-identical quadruplets worldwide. Many sets of quadruplets contain a mixture of identical and fraternal siblings, such as three identical and one fraternal, two identical and two fraternal, or two pairs of identicals.IVF is the typically the common cause of multiple births. Most recently, take the Parents who just found out they they were have quaduplets, after 8 years of infertility. Their reaction: Priceless.
But is DOES happen naturally for some. Take a Mother in the UK who naturally conceived a set of quaduplets just this year, all boys!
More cool stuff!!!!

I'll drop some more knowledge on you guys another time. :-)
