In brief: At most 1/2 hour

The skin rapidly produces sufficient vitamin d on sun exposure.
In 1/2 hour you have made 10, 000 units of vitamin d3, quite adequate for any known needs. After than you run the risk of sunburn, skin changes and possibly cancer later in light (if done often) although you might tan with repeated exposure (if that is one of your goals).

In brief: Difficult to Tell

The vitamin d our body needs can either be produced by sunlight or by consumption.
How many hours your child would need to be in the sun is influenced by surface area exposed, longitude, skin color and sun-block. Children from 1-18 are recommended to get 600 units/day; consider a daily vitamin. For light skin and direct sunlight, 10-15 minutes a day or 1-2 hours a week should be enough.
