the baby is bunny hopping.
Sure, a series of lurches, rolls and other manoeuvres means the New Recruit has been fairly mobile around the floor for the better part of the last month, but just now, as in j.u.s.t. NOW, he saw a rattle he’d t.h.r.o.w.n. across the room and decided he wanted it back.
So he just bunny-hopped his way over there.
