Stillbirth is typically defined as fetal death at or after 20 to 28 weeks of pregnancy.

It results in a baby born without signs of life.

A stillbirth can result in the feeling of guilt in the mother.

The term is in contrast to miscarriage which is an early pregnancy loss and live birth where the baby is born alive, even if it dies shortly after.

Preterm birth, also known as premature birth, is the birth of a baby at fewer than 37 weeks gestational age.

These babies are known as preemies or premmies.

Symptoms of preterm labor include uterine contractions which occur more often than every ten minutes or the leaking of fluid from the vagina.

Premature infants are at greater risk for cerebral palsy, delays in development, hearing problems, and sight problems.

These risks are greater the earlier a baby is born.

Miscarriage, also known as spontaneous abortion and pregnancy loss, is the natural death of an embryo or fetus before it is able to survive independently.

Some use the cutoff of 20 weeks of gestation after which fetal death is known as a stillbirth.

The most common symptoms of a miscarriage is vaginal bleeding with or without pain.

Sadness, anxiety and guilt may occur.

Tissue or clot-like material may also come out of the vagina.

An infant (from the Latin word infans, meaning "unable to speak" or "speechless") is the more formal or specialised synonym for "baby", the very young offspring of a human or other animal.

A parent is a caregiver of the offspring in their own species.

In humans, a parent is the caretaker of a child (where "child" refers to offspring, not necessarily age).

A biological parent is a person whose gamete resulted in a child, a male through the sperm, and a female through the ovum.

Parents are first-degree relatives and have 50% genetic meet.

A female can also become a parent through surrogacy.

Some parents may be adoptive parents, who nurture and raise an offspring, but are not actually biologically related to the child.

Orphans without adoptive parents can be raised by their grandparents or other family members.
