Having a small baby

Published: 24/10/2014

This information is for you if you want to know more about being pregnant with a small baby. You may find it helpful if you are pregnant and have been told your unborn baby may be small. If you are a partner, relative or friend of someone who is in this situation, you may also find it helpful.

  • It tells you about:
  • possible reasons why your unborn baby may be small
  • how to reduce the risk of your baby not growing well
  • how the diagnosis of a small unborn baby can be made
  • what extra care to expect if you are thought to be having a small baby.

This information is not for women who are pregnant with more than one baby.

This information has been developed by the RCOG Patient Information Committee. It is based on the RCOG Green-top Guideline No. 31, The Investigation and Management of the Small-for-Gestational-Age Fetus (2013).
