Floor-time=playtime, running around house, usually last a few hours.
Lap-time=holding time, cuddleing, usually takes place on ones lap
Free-range=its basically floortime 24/7. My boys used to be free-range during the day, but they started getting too brave and into trouble (ie. they stopped fearing walking on the hardwood floors...then when gated off them they chewed and tried to push over gate all day)
