These great hourglasses manages to make time understandable and clearly even young children. I take this hourglasses when my two children for. B. are fighting over a toy. Then a time will be determined according to the clock, then alternated after. Or if the kids do not even want to get out of the tub, then the clock will help them to understand that they still have z., 10 minutes, etc.
It works great and takes a lot of stress out of conflict situations.
The material is sturdy and so "beautiful" processed that children like to deal with it and play. Meanwhile, they bring themselves to watch, to arrange together, when they want to alternate z. B. the Bobbycar. Just a wonderful purchase!
