The effects that transitions may cause children to suffer are bed wetting, thumb sucking and talking like a younger child. This is regression.
Having temper tantrums and becoming frustrated is a sign of aggression.
Children may withdraw and become very quiet, not wanting to try new activities or joining in with their peers.
They may become clingy and require more reassurance than before.
They may have more coughs and colds than usual and complain of stomach pains. These may genuine or psychosomatic.
They may become extrovert by seeking attention or depression may become a problem. Self harm or food issues could become noticeable.
If the child or young person can develop one strong relationship, with a key during the transition process, then this can reduce the negative affects on the child dramatically. A key person is very important to any child or young person through any transition, as they will give them support, advice. The child needs to feel secure and the key person can also monitor any changes in the child.
For example in an early years setting a key person is important to a child, as they will see this person as someone to rely on, while their parents are not there.
