Fear is one of the four primary emotions. It represents an inborn defence mechanism as a kind of protection from different potential dangers, and it manifests on a physical, cognitive and behavioural level. Physically it shows through faster heart beat, redness, heavier breathing, sweating, muscle tension, etc. On a cognitive level it can manifestin form of forgetfulness, concentration difficulty, negative thoughts, self-consciousness, etc. In terms of behaviour it becomes apparent through crying and screaming, teeth chattering and lip twitching, stuttering, thumb sucking, etc. Fear occurs in the second half of the child’s first year, and according to available research, younger children and girls experience a bigger number of fears than older children and boys. We can commonly see developmental fears in children, what is a normal occurrence at a certain age. They occur, change and spontaneously disappear when a child outgrows a certain developmental phase. During every developmental phase there are specific fears that have a certain function for that age. Children can be afraid of unknown people, separation, darkness and imaginary creatures, injuries, catastrophes, failure, lack of acceptance, ridicule, etc. Although developmental fears usually pass by themselves, and are an integral part to a child’s development, they can become intense and lasting so that they interfere with the child’s everyday life. In those cases expert help is needed. Fears in children can be a result of crisis situations, such as illness or hospitalisation of the child, illness of family members, divorce of the parents, death of family members, violence in the family and abuse in the family. Traumatised children generally suffer from more visible fears and tension and often expert help is necessary.
