My baby is 9 wks old sleeps on back when will she stop jerking herself awake even when it's extremely quiet in the house?

In brief: Normal reflex

The startle or Moro reflex is active in infants for up to 4 months asleep and 3 months awake.
If you can limit the environmental sounds or movements nearby, she should not do this as much.
