Biting is very common in young children. Children may bite when they just can't cope with a situation, like when they're overcome by fear, anger or frustration. It is up to us to teach them that biting is wrong and that there are better ways to express negative feelings!
Social Stories are used for teaching kids behavioral expectations. They work great with kids with Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD) and Social Emotional Behavioral Difficulties (SEBD)
