Biting can scare adults, even more than it does children. Children readily pick up on our panic, allowing situations to escalate, if adults are yelling, hurting or scaring children. Working to stay calm can help children relax enough to learn from the situation. Give it time and get help if necessary. Despite our best efforts, biting doesn't always disappear immediately.
Some children bite one or two times and never try it again.
Others may bite on and off for a few months. If you feel like your child's biting is not just developmental in nature, but is connected to some other emotional issue he is dealing with, it might be useful to get some counseling. Sometimes counseling directly with children is helpful, but often, counseling for parents can help them work through issues and offer tools for them to help their child. Outside resource people can also support the child care staff can be effective in helping them come up with problem-solving strategies. Watch kids controlling behavior of breath holding.
