Bounds v. O'Brien, 134 S.W.3d 666, 670 (Mo.App. 2004). As we explained in Roy v. Nicks, 125 S.W.3d 399 (Mo.App. 2004), a trial court which is validly determining custody under the UCCJA also has the authority to adjudicate the issue of child support as an incident to the custody determination, provided the requirements of § 452.460 are met and the adjudication of support is in the child's best interest. Id. at 401-03; see also Elbert v. Elbert, 833 S.W.2d 884, 888 (Mo.App. 1992); Upchurch v. Upchurch, 767 S.W.2d 629, 630 (Mo.App. 1989); Nocito v.
