Losing Ground
Six weeks after a baby is born, a lot of things change. With respect to the baby, we have gaze-holding, smoother arm movements and cooing. Stuff is on somewhat of a schedule (though the schedule might change every day). With respect to the Mom and Dad, well, the Mom can start exercising, Mom can go back to work and Mom and Dad can err...get started up again.
Usually, baby is better with meeting these milestones than Mom and Dad are. Mom is hoping going downstairs counts as exercise. Work...well she has a whole month of maternity leave left (yoo hoo). As for point 3, a lot is usually said about the mood, the energy, and an opportune time...but one of the main reasons I can best depict with this sketch. Yes, we have space issues.
