Push!

We think it's well ahead of schedule, but what do we know? In any case, Mr. Lincoln enjoys his tummy time (unlike his older sister back in the day) and at 5 weeks (only 1 week, if you're counting from full-term!) is quite adept at grunting himself into a near push-up position. When bathing, he exercises his lower-body muscles as well, pushing off the ground with his feet as we support his tummy. Looks kind of like yoga's downward-facing dog.
