I think it depends on the child.
Each one will be different. I talked with our child a lot.. Even as an infant.
I would say each step of whatever I was doing. It felt strange to have a one sided conversation, but I could tell she was listening..
She was an early talker also.. By her 1st birthday she was speaking in sentences and able to come up with her own explanations..
At her party, my mom had made punch.. Our daughter had never had anything like it.. No sugary sweets, only fresh fruits.
When she tasted the punch, her eyes got really big and she announced . "Candy Juice!" she was so surprised..
We had never given her candy, but I guess after talking about how sweet candy is, she got the idea this punch must have been made out of candy..
She would reach up with both hands and say. "Hold you me, peas?" Her version of "Please hold me?"
Our neighbors little girl never tried to make out words, but was really fluent in baby sign language. I know it was helpful to her parents. My concern was that they never said the words.. If she signed bottle, they gave her the bottle, but did not say, "Here is your bottle!" They would say "here you go!" and sign the word bottle..
I never heard that child speak and they moved when she was just over 1 year old, But I do know their child is doing great in school, she is now going into 3rd grade this year and is in an accelerated program.
