Since 2009, 90-year-old Barbara Lowe has been a fixture at Hillcrest Hospital outside Cleveland, but she's not a patient. Almost a decade ago, the Mayfield Heights, Ohio, resident took it upon herself to begin knitting tiny hats for newborn babies delivered at Hillcrest, and has now delivered 2252 hats and counting, according to ABC News.

Lowe lives in a senior living complex across the street from the hospital, so it was an easy jump to go from whipping up hats for the children of her family and friends to delivering teeny headgear to the maternity ward.

Using fine baby yarns, Lowe makes ribbed hats with a brim and a detachable flower, spending around four hours on each one. They come in a variety of pastel colors. Lowe is known around town for her work with the hospital, and the manager at the Michaels store she buys her supplies from gives her a discount on the yarn she uses for hospital caps.

"It's my therapy," Lowe told ABC News. "When you're 90, you've got aches and pains. You don't want to think about it. Well, you're not thinking about it if you're concentrating on what you're doing."

Lowe learned to crochet and sew as a child, and later taught herself to knit. She considers it a "dream" to be able to give back to her community by gifting the hats to new parents and their bundles of warm-headed joy. According to the hospital, the hats do more than just keep babies toasty after their first bath—they provide a teaching opportunity to help new parents learn how to keep their babies feeling warm, as a hospital official told Cleveland.com.
