Measure the expansion joint separation at 2-foot intervals around the perimeter of the room, taking note of the widest gap between the hardwood floor and the baseboard. This is the dimension of quarter-round molding you will need to purchase; you will need lengths of molding equivalent to the running feet of baseboard plus 10 percent for cutting waste.
Cut the molding to fit the baseboard, using a miter saw and box to ensure straight cuts. For an outside corner, make the cuts on an outer angle; for an inside corner cut the ends to an inside angle. This will ensure a tight, neat fit of the molding.
Nail the quarter-round molding into place, taking care not to dent or gouge the baseboard as you work. Your hardwood floor separations will not be visible, and your floor will still have the space it needs to expand and shrink.
