Small babies - Low Birth Weight (LBW) or (SGA)
Small for gestational age (SGA) babies are those whose birth weight lies below the 10th percentile for that gestational age. Low birth weight (LBW), is sometimes used to define a baby that weighs less than 5 lb 8 oz (2500 g) regardless of gestational age. One third of babies born with a low birth weight are also small for gestational age.
Other definitions include Very Low Birth Weight (VLBW) which is less than 3 lb 5 oz (1500 g), and Extremely Low Birth Weight (ELBW) which is less than 2 lb 3 oz (1000 g).
About 10 percent of fetuses are low birth weight. A health care provider may suspect fetal growth restriction if the mother's uterus measurement (fundal height) is lower than expected. This can be confirmed with a series of ultrasounds that will monitor how quickly the fetus is growing.
The main causes for Low Birth Weight:
The two main causes of LBW are early delivery, also known as preterm birth, and poor fetal growth. About 70% of all LBW babies are born preterm - before 37 completed weeks of pregnancy. The remaining 30% of low birth weight babies are born at full term, but did not grow properly in the womb.

The babies were conceived naturally and the twins were delivered by Caesarean section at 25 weeks and six days on September 19 2004 at Loyola University Medical Center. |

Madeline 9.9 ounces (280 g) 27 June 1989 - Florida
Madeline Mann weighed just 9.9 ounces (280 g) and had a length of 25 cm when she was born in 1989, making her the smallest baby in the world at the time. Her parents conceived her by artificial insemination. Madeline started out as one of triplets. The two others died at 12 weeks' gestation.
Her 36-year-old mother developed pre-eclampsia, a potentially dangerous condition that raised her blood pressure and squeezed the blood flow to the developing fetus. Doctors decided to perform a Caesarean section at 27 weeks gestation, 13 weeks before her due date.

Amillia 10 ounces (283 grams) - Florida - October 24th, 2006
|Amillia Taylor is often reported as the most-premature baby. She was born on 24 October 2006 in Miami, Florida, at 21 weeks and 6 days. This report has created some confusion as her age was measured from a date of conception (through IVF) rather than the date of her mother's last menstrual period making her appear 2 weeks younger than if her age was calculated by the more common gestation method.|
Amillia Sonja Taylor was just 9.5 inches (24.13 centimeters) long and weighed less than 10 ounces (283 grams) when she was born Oct. 24. She was delivered after just under 24 weeks of pregnancy.
