Here is an example of a conversation in Engpsh that a 3-year-old girl might have:
Child: "Hi, my name is Sarah. What's your name?"
Adult: "Hi Sarah, my name is John. It's nice to meet you."
Child: "Do you want to play with me?"
Adult: "Sure, what do you want to play?"
Child: "Let's play dolls!"
Adult: "Okay, let's get the dolls out and we can play together."
Child: "Yay! I love dolls!"
I hope this helps! Let me know if you have any other questions.
