lol my kid does this too. he permanently thinks he’s a dinosaur.
I think it's pretty normal- a self defense mechanism
My son hates adult strangers and will be like “mom that lady is looking at me” and will point to them and say it loudly enough for them to hear. 😂😂 I rather him growl at people.
My daughter is 4 and hisses like a mad cat- no solution just know ur not alone
