In In re J.C. (2014) 226 Cal.App.4th 503, the court concluded the mother's "long-term sobriety and renewed interest in parenting classes showed changed circumstances, but Mother did not establish that an order giving her custody of the child would be in the child's best interests." (Id. at p. 526.) In J.C., the evidence showed the child "had a loving and stable placement with her maternal aunt . . ., who had cared for the child since her birth." (Ibid.) The child was two and one-half years old, and her aunt was "the only constant and stable parent the child had ever known," and the two "were strongly bonded to each other." (Ibid.) In J.C., the mother "failed to present any evidence the child's best interests in permanency and stability would be furthered by the proposed modification . . . ." (Ibid.)
