October is Down Syndrome Awareness month. Down syndrome is the most commonly occurring condition that is caused by changes in a person’s chromosomes. Specifically, it is caused by having three copies of chromosome 21 instead of two. One out of every 691 babies born in the United States is born with Down syndrome.
All people with Down syndrome experience some degree of intellectual disability. This means they will learn more slowly than other people. Children with Down syndrome will learn to do most things that other children do, but they will do them later than their peers.
