ing. On June 18, 2007, the court modified the child support order downward to $1,686.99 per month. It also awarded Mother her attorneys’ fees. Father filed a motion for new trial, to which Mother did not substantively respond, and a response to Mother’s fee application, to which Mother did not reply. Before the court ruled on the motion for new trial, Father filed a notice of appeal on July 19, 2007. Mother filed a notice of cross-appeal on August 14, 2007.
¶ -5 On September 11, 2007, the court ruled on Father’s motion for new trial. Though the court ruled against Father on several significant issues, including the calculation of his gross income and the attribution of income and childcare costs to Mother, it ruled in his favor on a few minor adjustments to educational and childcare expenses that had the net effect of lowering his support obligation further still. In the September 11 minute entry, the court also vacated the fee award in Mother’s favor. On September 17, 2007, unaware of the court’s ruling, Father sought to withdraw his motion for new trial. The September 11 minute entry was filed on September 21, 2007. On September 21, 2007, after learning of the ruling, Father sought to withdraw his previous motion to withdraw the motion for new trial. Mother objected and on September 27, 2007, filed a motion to strike the court’s September 11 order.
¶ 6 On October 9, 2007, Father filed a supplemental notice of appeal from the September 11 order and from the earlier order modifying his support obligation. On November 21, 2007, in an unsigned minute entry, the court granted Father’s request to withdraw his motion to withdraw his motion for new trial and denied Mother’s motion to strike the ruling on the motion for new trial. On November 30, 2007, Mother filed a notice of appeal from the November 21, 2007 order.
¶ 7 We have jurisdiction over Father’s appeal pursuant to A.R.S. § 12-2101(C), (F) (2003). We discuss our jurisdiction over Mother’s cross-appeal and her appeal from the November order below.
¶ 8 Father’s appeal argues that the family court abused its discretion by: (1) attributing hypothetical childcare expenses to Mother; (2) erroneously computing Father’s income; and (3) denying his request for fees.1
¶ 9 Mother raises a like number of issues in her cross-appeal, but she did not file a separate brief on her direct appeal. We first address the jurisdictional issues presented by Mother’s cross-appeal and separate appeal.
II. DISCUSSION
A. Jurisdiction
¶ 10 We review de novo trial court rulings involving questions of pure law, including the court’s jurisdiction to enter its orders of September 21, 2007 and November 21, 2007. See Hall v. Lalli, 194 Ariz. 54, 57, ¶ 5, 977 P.2d 776, 779 (1999). We also review independently our own jurisdiction over the parties’ appeals.
1. Father’s Premature Appeal
¶ 11 In Barassi v. Matison, 130 Ariz. 418, 419-20, 636 P.2d 1200, 1201-02 (1981), the supreme court held that a notice of appeal filed after the denial of a motion for new trial but before the entry of final judgment was sufficient to secure appellate jurisdiction. Because the lower court’s substantive decision had become final, and only ministerial tasks remained to accomplish the entry of a final judgment, the court reasoned that dismissal of such a premature notice of appeal would “punish the appellant for being too diligent.” Id. at 421, 636 P.2d at 1203. The court pointed out, however, that appellate courts lack jurisdiction when “a litigant attempts to appeal where a motion is still pending in the trial court or where there is no final judgment.” Id. at 422, 636 P.2d at 1204; see also Baumann v. Tuton, 180 Ariz. 370, 373, 884 P.2d 256, 259 (App.1994) (concluding that appellate courts lack jurisdiction over an appeal that was filed while the appellant’s time-extending motion was still pending in the lower court, and that such a premature notice of appeal is a “nullity”).

Father’s opening brief was filed while Mother's motion to strike the order ruling on Father’s motion for new trial was still pending. The other issues Father sought to advance in this appeal are moot as a consequence of the trial court's ruling on the motion for new trial.
