Monster Update: Week 13

The Monster is only about 3 inches long crown to rump — roughly the size of a jumbo shrimp (pictured) — and weighs just about an ounce. Despite the small proportions, there's a fully formed baby inside Stef's womb now. Much more proportional than it was a few weeks ago, its head is now only about a third the size of its body. Tiny, unique fingerprints are already in place. Kidneys and urinary tract are functional, and it's starting to urinate out the amniotic fluid it's been swallowing. That's not gross at all!
