Jonas started crawling the other day. He literally went from only being able to lay flat on his stomach, cursing his immobility, to crawling at about 10mph, which at scale is more like 2000mph. He’ll tear across a room towards a toy on the ground only to completely redirect himself and his momentum toward another toy that catches his eye midway through is mad trek.
Also, totally coincidentally, our floors are cleaner and Jonas has cut back on the quantity of food he eats during meal time. Mysteries, these little humans.
