I want to get my 6 year-old a watch with a touch screen, that looks cool and gets him excited about going to the toilet! (We have chronic constipation issues and he needs regular reminders and this is what we've agreed on together). The smart watches look good but I don't want him getting addicted or distracted. At the same time this is a bit of a treat for him so something that has some extra features would really go down well! Nothing too expensive (not over $100). Any ideas?
