What's the procedure like?
You may be advised to eat a meal just before the test in the hope that eating will stimulate your baby to move around more. (Although there's no hard evidence that this works, it can't hurt.) It's also a good idea to use the bathroom beforehand, because the test may take up to an hour.
The test starts with an ultrasound to observe your baby's body movements, muscle tone (flexing the arms and legs), and breathing movements (the baby's ability to move her chest muscles and diaphragm), and the amount of amniotic fluid surrounding her.
