The nurses explained that these methods must only be used when the child's needs were well understood. The nurses stressed that the children had to feel safe and in control. If not, the children could feel deceived when the nurses tried to get their attention and shift it away from what was actually going on during the procedure. The nurses found it challenging to keep the child's focus away from the situation while simultaneously providing a satisfactory level of predictability and control. When deciding on the type of approach, the nurses evaluated the individual child's needs rather than taking a pre-determined approach. For example, a very scared child did not benefit from being distracted or having his or her focus directed from the situation. One nurse explained how she decided on the type of non-pharmacological method after a quick try-out phase", first using standard methods such as soap bubbles.
