As the Moms point out, in the minds of especially younger kids, there are really only two times: "now" and "not now." And knowing the difference can be really challenging for kids (and parents) to navigate!
One helpful strategy the team points out in their review is using “When/Then” phrases, such as "When your dirty clothes are picked up, then I will read you a book." This can be a great way to use sequencing instead of duration for a child who cannot grasp the passing of minutes. "When we have finished dinner, then Grandma will arrive."
Now, there's an app for that. Thanks for the review, Rookie Moms!
