A GeneaNet feature can easily let you know how many descendants are belonging to an individual in your online family tree, including all of the children.

This can be useful when organizing a family reunion or sharing data with some other genealogists.

In your GeneaNet online family tree, select an individual then click on the link "Descendants (Tree)" at the bottom of the page.

The "Specify generation" drop-down list automatically show the number of descendants by generation.

Select the number of generations and the display options, then click the button "OK".

This will open a new page with the list of the descendants.

The number of descendants, including all of the children, is shown at the bottom of the list.
