When the Make-A-Wish Foundation offered 4-year-old Dominic Kerr a wish, the sweet child decided to bring joy to other children.

Dominic, who was diagnosed with leukemia two years ago, chose to spend his wish on toys for patients at the Children's Hospital of Pittsburgh Marty Ostrow Hematology/Oncology Outpatient Center in Pittsburgh, Pennsylvania, according to Make-A-Wish Foundation Greater PA and WV's Facebook page.

Earlier this week, Dominic went on a shopping spree at Toys R Us and Walmart so that he could fill a treasure chest with purchases, CBS Pittsburgh reported. He got a similar gift when he was in the hospital and wanted to return the favor.

"Dominic wished not for himself but for other children," regional Make-A-Wish President Judith Stone told the outlet. "He had a memory of coming to children’s hospital, and one of the highlights was going to the treasure chest."

All Dominic's donated toys will have a sticker on them that reads, "Donated by Dominic," according to WTAE 4.

"Just seeing him, as happy as the toys made him, I hope it makes other kids as happy," Dominic's father, Mick, told the outlet. "And hope it gives them hope and makes it an easier time in the whole situation."

When asked why he chose this as his wish, Dominic said, "Because I want to make other kids happy."

What an incredible kid! Check out the pictures below of Dominic's big day handing out toys at the hospital.
