On the influence
Show to children that doors and windows of their house are locked, and, so, at night nothing threatens them.
Children can design also for themselves the alarm system or systems of intimidation of burglars.
On the influence they are similar to the magic means allowing the child to return selfcontrol.
It is important that a bed, a bedroom became a place where the child calms down, but not a place where he serves sentence.
In the latter case the bed and a bedroom can cause in it negative emotions.
And the room causing such emotions becomes a receptacle of various fears.
