Armadillos have four babies at a time, and they are always all the same sex.

Sometimes, it's really amazing what technology can do these days. 

One generation ago, one could only hear a baby's heart beat through a stethescope. Nothing more.

Now, we have ultrasound scans which shows us clearly what the baby is doing in the womb. 

We are able to measure the skin thickness behind the neck, and correlate it for risk of autism. 

We are also able to scan the baby in detail, for any deformities to the limbs and organs. 

Cord blood can be extracted during delivery, and preserved for stem cells. 

Who knows what else the future will bring?
