Had to know what happened to the other kid(s) and whether it was just one:

"Their first son, Nevada Alexander Musk, died of sudden infant death syndrome (SIDS) at the age of 10 weeks."

More interestingly, the five are two twins and three triplets.

Wouldn’t that mean fertility drugs were probably involved? Anyways, I guess he really likes kids, which is a bit surprising.

“They later had five sons through in vitro fertilization – twins in 2004, followed by triplets in 2006.” is the sentence following the quoted one in that wikipedia link.

Why is it surprising? Liking offspring is the underpinning of all of human evolutionary history.

He loves to experiment.
