People with Down syndrome are not all the same. People with Down syndrome have more in common with their families than with each other. Just like the rest of the population, they will inherit family characteristics. Everyone with Down’s syndrome will have some degree of learning disability. The learning disability affects a child’s ability to learn compared with other children of their age, it does not mean they cannot learn. But the most important thing to remember is that everyone with Down syndrome is a unique individual.
Children raised at home and included in all aspects of community life can best reach their potential and function in society with a greater degree of independence.
Parental love, nurturing and support, as well as early intervention programmes, education opportunities and community involvement, have a direct influence on the degree to which a person with Down syndrome is able to achieve his / her potential.
