Like others have said, listen to your patient or parent of the patient. I will never forget when my daughter was five and in the hospital. I left to get a cup of coffee. When I walked back in the respiratory staff person was trying to get her to inhale something she did not take. She was telling them "I don't take that."--even at five she knew her meds and the names. They weren't willing to listen at first, until I further clarified for them. This is a small example, but I think one of the main things is that the staff has regimented ways of doing things, but through daily care we have our routines in place and that should be honored as well.
Oh yeah, and most importantly, make the little ones laugh!--Your trust and respect will go far!
Hope your presentation goes well.
