Overall, the weight of evidence is that
no significant relationship can be found between the physical characteristics
and the person's mental functioning.

How did the doctors know my baby had Down syndrome?
Many babies with Down syndrome have
certain physical characteristics which are common in Down syndrome. These
signs occur in up to 80% of all cases. Individual characteristics are often
found in children without Down syndrome but the Down syndrome child will
have several. These traits are:
If a child has six to ten of these
signs, the doctor can be almost certain that the child has Down syndrome.
What effect will these physical characteristics have on my baby's health?
Children with Down syndrome can be prone to breathing problems due to the smallness
of the mouth and the poor development of the sinuses. This can lead to mouth breathing
which will encourage the protruding tongue often seen in children with Down syndrome.
The protruding tongue in combination with low muscle tone in the muscles of the face
can cause nursing problems since the child with Down syndrome may have trouble getting a
tight seal on a nipple. The baby may also have a weak suck due to hypotonia and may later
have trouble eating solid foods. A therapist can help with this problem.
What is hypotonia?
Low muscle tone or hypotonia, is very common in children with Down syndrome. Their muscles
feel floppy. Although the degree of hypotonia varies from child to child, it generally affects
all muscles in the body. Hypotonia may contribute to delays in motor development but with the
help of a therapist, improvement in your baby's motor skills will be achieved. Therapy for
hypotonia should begin within the first few weeks after the baby is born. A therapist can show
you techniques (such as holding the baby in a certain way) that can be beneficial to your baby's
development. Low muscle tone can effect eating and speaking skills so a speech therapist should
work with your baby. Hyperextensible joints can also effect your baby's development. Your baby's
joints may be very flexible. This flexibility can make it difficult for your baby to be stable enough
to learn how to walk. Professionals such as Occupational and Physical Therapists can help alleviate
these problems. Early intervention is the key.
