you can feed your kids the actual fruit too. No need to make a "dessert" specifically.
AND fyi any dry fruit is very high in sugar because the sugar concentrates when the fruit is dried.
Your body does't care if you get the sugar from a cookie or a fist full of dates, its all the same to the body.
Do you also control how much pasta, rice, potatoes, peas, carrots, winter squash, sweet potatoes, bread and corn they eat? That all is turned into sugar by the body so that it can be used. AND if you think whole wheat bread is better, it actually has a higher glycemic index than white bread does.
