I'm a little OCD on keeping track of the time, not sure why. One thing I enjoy is wearing a watch. I'll look at it half a dozen times in a row to make sure I read it right, but I also enjoy wearing it because I think it looks neat and I like seeing it and watching it tick.

Maybe a cheapish watch that the kid likes, and would want to wear rather than needing to remember to wear it, could help? A little dose of "that's neat" while also seeing the time.
