Oh yes, a brief phase for mine at least. Soon after she learned to walk, which in her case was walking and running all in one day. An over-exuberance of that new freedom and power. Feeling the rush of air on her wings, as it were. She would usually leave her diaper on, unless it was moist and heavy enough to slow her down. Of course the phase coincided with our being on a pre-planned trip, constantly in public situations where I didn’t know the territory. At least we spoke the language!
