When working with babies and young childen they are almost entirely dependent on adults to care for them in ways that help to protect them from harm. This could be physically or psychologically. When working with children, we safeguard them in various ways such as:
Carrying out risk assessments in the setting to ensure that toys and equipment are safe.
Assessing that the setting has no potential hazards (socket covers on plug holes, hazard materials etc)
Setting boundaries and clear expectations for children's behaviour which could upset other children or cause then distress.
Observing children and assessing their development. Being observant to any indications that their progress is not correct for their stage of development.
Understanding the different ways that children can be abused by others. The signs that a child may be experiencing harm and knowing the correct procedures to deal with it.
Hope this helps. If you get the book it will help a lot on this section.
