Your body your rules: My body my rules - Sometimes children express their affection, anger or even excitement by pinching, biting or hitting an adult or child. For example, my son loves to poke at my underarm and squeeze my arm hard, which I don’t enjoy. Yes, it’s just playful, but do I have to grit my teeth and bear it. The child thinks- “I am only expressing my feelings. When others can do what they want to me, even when I don’t like it. Then I can do the same”.
