With your child's changing psychology and growing understanding of things, a lot of things come to surface. Alongside fear over general stuff, she may also be dealing with nighttime fears.Your child’s bedtime fears like the dark, monsters under the bed, and sleeping alone are all common at this age and are a part of her growth process.
What you need to know
These are the years when your child's power of imaginations are exploding, which means that now your child can imagine new and scary things to be afraid of. And because they spend a good portion of their day immersed in fantasy play, it can be hard for your child to shut off their imagination at bedtime and go to sleep.
Distinguishing fantasy from reality
Even familiar things that have never been scary before, like their darkened bedroom, may suddenly seem frightening against the backdrop of what they have been conjuring up all day. And your child is still learning to distinguish fantasy from reality, so the possibility of an invisible creature under their bed seems quite real to your child. Fear of the dark, of separation from you, of noises, and of bad people doing bodily harm is a normal developmental stage that goes on much longer than you expect, starting at around age 2 and going until age 8 or 9.
The best way to curb such fears from their minds is by helping them comprehend that reality is way different than fantasy and also boosting their courage by motivating them to face their fears.
