Being left-handed does not mean being left out. At Fisher-Price, for example, we test toys on children who are both right- and left-handed—and make every effort to ensure that the toys provide easy access and use. We also offer children's utensils and cups that can be used by both right- and left-handed children. Also, most of the scissors currently made for children are designed for use with either hand. Your grandson is not being discriminated against for being left-handed; it's just that many of today's products are made for either hand, so there are not as many specialized left-handed items as in the past.
Our parenting advice is given as suggestions only. We recommend you also consult your healthcare provider, and urge you to contact them immediately if your question is urgent or about a medical condition.
