Can anyone help me brainstorming ideas on my product for the Graduation Paper?

my topic was pediatric nurse, i chose it because i want to write something that related to my career in the future and i need help on the product part..i was thinking about visiting the hospital (children) and make videos and taking picture but i need more than that...im stress out i might change my topic if i cant find something good but that would be starting all over again and i dont want that,,,
