"A parent's exposure of children to drug use may be properly considered in determining whether a parent demonstrates appropriate parenting abilities." In re O.N.V., No. 12-24-00214-CV, 2024 WL 4002387, at *4 (Tex. App.-Tyler Aug. 29, 2024, pet. filed). Before removal, the children were exposed to severe domestic violence; after removal, C.R.Y.B. did not complete a domestic violence course. A history of domestic violence and the failure to take a domestic violence course or engage in a domestic violence program supports a best-interest finding.
