Separation anxiety is the common and normal fear that children have of being away from their parents or carers.
Separation anxiety can start at around 8 months and reach its peak in babies aged 14-18 months. It usually goes away gradually throughout early childhood.
Stranger anxiety is similar to separation anxiety. It’s when children get upset around people they don’t know. It can happen from 7-10 months and usually starts to go away after the child’s first birthday.
These anxieties are a normal part of development and are nothing to be concerned about. Children are starting to move around more at this stage, so these anxieties make sense from a survival point of view. That is, if children could crawl or walk away from their carers but weren’t afraid of separation or strangers, they’d get lost more easily.
