So sorry you and your child are navigating this situation. Please choose one of these shelter options over staying in a hotel/private place. If not for support, do it for documentation. Hope for the best (partner recovering and family reunification if that’s what you all want and need) but plan for the worst (legal battle over custody). Having this incident and repercussions with your child on record is the best thing you can do to safeguard yourself in future possible proceedings.
