If you're looking for a paint program which both you and your children can enjoy, then you should take a look at Infinity Brush.
It's an easy to use but feature-packed paint program that aims to get you painting with the mouse in no time. It's actually similar to MS Paint but much more advanced with lots more templates and features. Once you've opened the main canvas, simply select a tool on the left such as an airbrush or pencil and hold the left mouse button down to drag and draw.
One unique feature of this particular paint program is that any image or copied shape can be used as a paint brush instead of the boring old cursor. In addition, images can be resized instantly which makes it handy for making thumbnails or avatars. You can apply several special effects too such as mirroring, warping, stretching and rotation. You can even make images transparent and then place them on the canvas so your kids can color them in. If you've got dual monitors, or even just one to work on, there's also a "Swap Screen" option which allows you to work on two images at the same time - a fun way to practice drawing with young ones.
If you're looking for something a bit more fun than MS Paint or a drawing program the whole family can enjoy, then Infinity Brush is a reasonable option.
- Two new Curve drawing Shapes functions were added along with a 'Dragonfly' decorative action similar to the Stars and Hearts shapes functions. A shapes "Copy to Clipboard' option was added to facilitate use of the decorative functions. With this new option ON, decorative figures are automatically copied to the clipboard allowing them to be readily available for all 'Edit' capabilities.
