This is something that mommy is worried about. You can ask me a million times "What is your name" in a million different ways and I will not answer you unless you know exactly how to ask me. You have to show me what you mean. "My name is mommy. What is your name." I have a tag that we put on my shoe and a temporary tattoo with mommy's phone number on it that I wear for big events. That way if we get separated another mommy can find my phone number and get me back to my family.
