When do little ones start saying multiple syllable words or phrases. I notice more that mine only says 2- 2 syllable words: cookie and kitty. When we say things like “l love you” he just says “you” or we just got a dog named “Lana” and he calls her “na”

Like he only says the last word in a phrase or the last syllable...

So just wondering peoples thoughts or experience with learning speech. He says a lot of words most 1 syllable so im not worried - just curious.
