Child abuse

So I’m currently in a situation where child abuse is happening and administration is hiding it because they favor the teacher.

The incident happened during a sing a long where the teacher bent their head and the one year old grabbed the teachers hair. She became frustrated, grabbed him by his hair and body slammed him to ground. In the moment I was in shock as well as the other teacher in the room and we continued about our day. The next day I reported it, as well as my coworker to one of the directors and during our conversation she tried to give me words to use instead of mine own. She claimed we would have a meeting that same week about it. A week passed and nothing happened so I confronted the other directors about it and let them know I do not feel comfortable working with her. They were all shocked about it because that one director never told anyone about it.

So we had a second meeting where she explained that she had a lack of communication with me and everyone and apologized and that they spoke to the teacher but would not be removing her because they had a conversation and have known her for 3 years and trust her. So right now I’m being treated weird by administration and have been moved from that classroom and hoping my hours aren’t gonna be cut. I reported to child line as well as made a report online against the daycare. Is there anything I should have done differently? It just seems like these daycares care only about their image and teachers they favor and not the actual child getting abused and it’s becoming disheartening and making me not want to be In this field.
