Be patient: Children can be unpredictable, so it's important to be patient and understanding.
Show interest: Ask the child about their interests and listen actively to what they have to say.
Follow their lead: If the child seems hesitant to engage with you, respect their boundaries and give them space. They may just need time to get comfortable with you.
Be respectful: Remember that the child is not your own, and show respect for their relationship with their parent.
Keep it light: Try to keep the mood light and positive, and avoid any heavy or controversial topics.
Overall, the most important thing is to be respectful, patient, and understanding, and to approach the relationship with an open and positive attitude.
