Monster Update: 32

By now, the Tummy Monster weighs 3.75 pounds (about the size of a large jicama, pictured) and is about 16.5 inches long (give or take), taking up a lot of space and moving around a ton. Stef has been healthily gaining about a pound a week and roughly half of that goes right to the Monster. In fact, he'll gain a third to half of his birth weight during the next 7 weeks as he fattens up for survival outside the womb.
