Leo: (Gesturing to his testicles) This? Me: Those are your testicles. Leo: (Happy/Cheery tone and gesturing with both hands) Two testicles! me: Yes, you have two testicles. (I start putting his diaper on) Leo in same cute little happy/cheery tone: Bye bye testicles! (note: Leo is difficult to understand, so this is more of a translation than a direct quote... the meaning was there, just not the enunciation!)
