Smoking during pregnancy reduces the growth and health of babies and increases the risks of a number of complications and illnesses for both the mother and baby. Babies born to women who smoke during pregnancy have a greater chance of premature birth, low birth weight, stillbirth and infant mortality.
Around 8% of babies in Australia each year are BORN EARLY. Babies born prematurely may need help to breathe and are at much higher risk of long-term health problems than babies born on time. Premature labour occurs before the 37th week of pregnancy and occurs in 5%-10% of all pregnancies. A pregnancy generally lasts between 38 and 42 weeks.
