Mary Santelman discusses all forms of biting, the labeling of a biter, the biter as victim or victimizer, and record keeping of biting behavior. On the list of toddler behaviors, she also examines tantrums, including insights into the child's emotional needs, calming down, kicking, hugging, throwing things, and hurting people. Mary describes calming behavior by nurturing feelings of safety and trust, guiding the child to meaningful work, accepting mistakes, playing outdoors, and assisting with social interactions that give a sense of belonging, positive learning, and clear boundaries.
