Although this Court's authority is as broad as that of the trial court in custody matters ( see, Young v Young, 212 AD2d 114, 117; Matter of Rosiana C. v Pierre S., 191 AD2d 432, 433), the general rule is that custody determinations are ordinarily a matter of discretion for the hearing court, the determination of which is based upon a "firsthand assessment of the parties, their credibility, their character, and temperaments", and should be accorded great deference ( Matter of Krebsbach v Gallagher, 181 AD2d 363, 364).
