"We were there just as much if not more than our own house, so the people at the hospital became our family," the boy's mother, Amy Newswanger, told CNN.
The family checked with the hospital and made sure the dinosaurs and Play-Doh were OK to donate, then got to work.
They ended up collecting 1,263 containers of Play-Doh, 71 superhero toys and 1,249 dinosaur toys, CNN reported. They delivered the toys Tuesday.
"Play-Doh is used by the child life specialists. It helps with distraction, it helps with kids to relax and manipulate it, and it's also one of those toys that not every kid is allowed to play with at home because it's messy," Sarah Miller, who works at the hospital, told WHTM. "But here at the children's hospital, it's alright to be messy, so we go through a lot of Play-Doh, so this is a big, big help to us."
