Origin story

Jack sleeps on his back, of course, and when he starts to get a little restless, he lifts both legs in the air and then drops them hard back on the mattress.  It doesn’t wake him up, but god damn if it doesn’t shake the whole house.  The first few times it happened, we went looking for what heavy thing had fallen over.  But then it happened again, and then again.  (He rarely does it just once when he’s stirring.)  So we checked the monitor and sure enough, our mini-earthquakes were being caused by the baby.

Every night, people.

His superpowers are developing.
