Start caring for that little mouth at around age 1. Use gauze or a soft infant toothbrush and water to gently rub the gums once or twice daily. Early care might prevent brushing battles down the road and could also be the golden ticket to easing teething pain. "I introduced a toothbrush to my son when teething was at its worst," says Morgan Eklund, of Durham, North Carolina. "He now thinks of brushing as an amazing source of relief." Also try cool chewing rings or washcloths when baby is cutting his teeth.
