Quite a few of these teethers do work wonders for older kids with oral motor problems. They’ve even been known to calm down children with the developmental disorder when they act out at home or in public. Of course, you should always get your doctor or therapist’s approval beforehand. Kids with autism, for example, may need a really thick, meaty chew to calm them down when they’re at peak frustration levels. In such cases, it’s nice to have different chewing levels to fit your child’s needs.
