Should I share this with DFCS? (Division of Family and Child Services)

I have a written document of things my mom has either done or continues to do to this day and some of it involves concerns about my niece and nephew, who are both children under her care due to their parents being unavailable. Does any of this seem worth sharing to a dfcs caseworker? Please let me know. Thanks in advance! https://docs.google.com/document/d/1l78wX5j0aIP9zo-UnSoli_4Ch9ZHm3DNiwcaI3AGCMU/edit?usp=sharing
