Time. Separation anxiety is a natural part of normal development. With time your child will learn that you will indeed return after you leave. Make sure you hug your child good bye and let them know you will be returning. Give them a big smile when you return! soon they will learn that you will always be coming back to them!
Time and patience. Separation anxiety is not a defect or linked to adult problems, it is a normal stage in a childs growing awareness of how important primary caregivers are to their life.For infants, their brain may not let them understand you still exist when they can't see you.Toddlers ofter fear that others are not as dependable to care for their needs.This passes with better communication skills &experience.
