Quoted:
Probably talk to her like an adult rather than using baby talk. That's what we've always done with our kids and people were constantly amazed that our 2-3 year old son or daughter (depending on which one at the time) said things exactly like the OP said. We've always talked to them normally and they pick up on that. They figure out what those words mean when you use them in context. And, they'll use them in conversation. Our kids can carry on conversations with adults just fine.
Exactally,
My 14 year old daughter, commented about my 2 year old Grand daughter, " She can carry on a conversation as good as some of my friends"
She correctlly uses words I can't spell
, and recently discovered adjectives , and one of her favorite games is rhyming words. See I can't even spell rhyming
