In situations where relatives demand affection from your child, it's important to advocate for your child's right to choose whether or not to show physical affection. You can explain to relatives that you're teaching your child about consent and body autonomy, emphasizing the importance of respecting the child's comfort level. Offering alternative ways for your child to show affection, such as a high-five or a verbal greeting, can help maintain family bonds while respecting your child's boundaries.
