What is a birth defect?
-
Birth defects are also called "congenital anomalies," "congenital defects," or
"congenital abnormalities."
-
A birth defect is a health problem that happens with a baby's growth or
development before birth.
-
A baby who has a birth defect is born with a health problem.

Birth defects can be mild to severe. Some may be hard to notice while others
can be life threatening.
What causes birth defects?
Many causes are not known. Doctors do not know why some babies are born
with health problems. Some defects are caused by environmental factors. Others
are caused by genetic factors.
-
Environmental Factors
-
If mothers are exposed to specific things while they are pregnant, it can hurt
the baby's health.
-
Examples include medications, drugs, diseases, radiation, or infections.
-
Defects can be caused by injury to the unborn baby.
-
If the mother does not eat healthy during pregnancy, it can cause birth
defects.
-
-
Genetic Factors
-
Every person has different genes. Genes decide what people will look like,
their health when they are born, and how they will grow and develop.
-
Problems with a parent's genes can be passed down to a baby.
-
Sometimes, the baby has problems with his genes even if his parents are
healthy.

How can parents and families cope?
-
Parents may have to leave their baby at the hospital if he has a birth defect.
This can be a very hard experience.
-
Families may feel guilty, angry, disappointed, and overwhelmed.
-
Doctors, social workers, and support groups can help families deal with these
feelings.
-
It is important to offer support not only to parents, but also to siblings and
relatives.
-
Learning about the birth defect is often comforting and helps families feel
more in control of their baby's health.
-
Families are usually encouraged to spend as much time as they can with the baby
at the hospital. Sometimes, mothers can receive postpartum (after delivery)
care at the hospital with the baby.
-
If a mother wants to breastfeed during the child's stay at the hospital, she
should talk with doctors about options. The doctor may recommend using a breast
pump.

It is important for families to maintain their own good health. Eating healthy,
exercising, and getting plenty of rest will help them deal with stress.

Once the baby is home, families should continue to seek support. Schools and
community centers, as well as doctors and social workers, are good sources of
