If parents have small stature, the baby may be small. These babies have normal development but are just small compared to others their age.
SGA sometimes occurs if there are growth and development problems before birth. These may occur with:
- Problems with the supply of nutrients and oxygen to the baby or a small uterus—can cause a condition known as intrauterine growth restriction (IUGR)
- Birth defects
- Genetic syndromes
