How do I know my baby is smaller than his gestational age?

Your baby may not feel as big as it should be. A measurement of the fundal height (measurement from the mother’s pubic bone to the top of the uterus)  by your health care provider will be smaller than expected for the baby’s gestational age. Ultrasound calculations will be smaller than would be expected for that gestational age.

 

I have intrauterine growth restriction. What next?

Treatment depends on how far along you are in the pregnancy.
If you are less than 34 weeks pregnant, your doctor will closely monitor you until 34 weeks gestation or beyond.  If there is any cause for concern, you will be delivered immediately.
If you are 34 weeks or greater, your doctor will recommend induction for early labor.

  • increased  risk for meconium aspiration
  • low blood sugar
  • increased number of red blood cells
  • decreased blood flow due to an increased number of red blood cells
