    So “16.4 mph north” is sufficient.

    No, it’s not. “North” is a two dimensional direction on the surface of the earth. But we live, and can throw babies, in three dimension. Therefore you need to specify the inclination as well. “56 furlongs per minute, north, 0.3 radians” would suffice.

      The surface of the Earth is 3d object, thus moving North is a 3d vector which modifies the baby’s velocity relative to the Earth’s center of gravity as it curves the movement of the baby flying through the air.
