In a motion for joint physical custody of a minor, is the mother's claim that the juvenile court abused its discretion by denying her request for joint custody of the minor?

Although mother states that the juvenile court abused its discretion by denying her request for joint physical custody of minor, specific arguments in support of this position are difficult to discern from her briefs. Given mother's failure to present cogent legal authority or argument, we deem the issue forfeited. (See People v. Stanley (1995) 10 Cal.4th 764, 793 [a court may treat as waived a point in a brief made without reasoned argument or authority].)
