Linux and apps for an infant

I’ve got a little one who wants to be like her dad and click-clack at the computer. Old enough to know what the keyboard does but not old enough to type anything meaningful.

Does anyone have a go to distro or simply a recommendation of an application for kids that allows input and “makes something happen” which also requires an incantation to close or is otherwise as hard to close as bloody Vim?
