Why replace an electric mixer or wire whisk? Because they're messy. When kids use these tools, food ends up splattered all over the kitchen. As for replacing the food processor, any time you can offer kids an alternative that doesn't have sharp blades, it's worth it. And blenders require the user to have enough height and manual dexterity to get food into them without spilling and to keep a hand on the lid while the blender is working.
What's more, the Todd English immersion blender is great for adults who regularly cook for kids, because it makes it easy to prepare everything from pureed soups to frothy milk steamers without having to haul out larger appliances that require more clean-up. With the Todd English immersion blender, you just twist off the blender foot and drop it in the dishwasher.
I like the fact that it is safer for kids to work with, too. The blade is housed under a metal dome. That's why food doesn't splatter. It also keeps kids from needing to touch the blade.
And this blender is cordless, so kids don't have to be tethered to an electric outlet to beat their cake batters.
The second drawback of the Todd English blender is the price. It retails for $117 from HSN, but you can easily find it much cheaper on eBay (yes, brand new).
