When we say something which relates to animal, Vyktore likes to make sound or say the word like us. But sometimes we find it so funny cause he gives the wrong sound. The one which he can get most correct is Dog (ow ow), Lion (arggh…..arghh…-sounds like lion in pain LOL).
Cat (suppose to be meow) turns out to be pssst…pssstt…

Tiger (suppose to be graaaa…graaa) turns out to be oo…ooo…

Cow (suppose to be moo) turns out to be hmmm…hmmm…..
Comparing to Faythe, his language is really development from a baby language (not speaking correctly with missing pronunciation) then move to proper words which we could understand, of which so far we only understand a few. Faythe was in fact pretty amazing, she never spoke any baby language and she started human-understandable word when she starts talking.

Every child is definitely different.
