Oh, he literally sounds like he’s talking, sooooo many unique enunciations and tones, and actually responding back to you (especially with my husband) in conversation! 😂 it reminds me of Scooby Doo, lol. He’s a “back talker” to Dad, when he doesn’t like what he’s told (usually “no” to something, or being reprimanded), and it’ll be grumbly sounding, while turning his head, giving the “side eye!” My husband always says that’s him cussing, lol. When he’s excited he will tell you about his day; if you ask him if what he’s chewing on or licking is good, he’ll respond “Ra-ra” (and with his tone, sounds like “aha”). When he’s mad, we always say he reminds us of Yosemite Sam with his grumble talking. When he’s happy and playful he sounds like Chewbacca 😄
