Thank you for your question.
Child abuse is a broad topic that you will have to narrow down lest you get overwhelmed.
As an example, I searched child abuse AND neglect in the search everything tab from the library main page.
I would further narrow your search by selecting peer reviewed and full text from the limiters located on the left of the screen to find the best articles about your topic.
You should find plenty of resources to write your paper.
Good luck with your research.
