Ah, kids. They're cute, curious, and when it comes to childhood illnesses, very, very contagious. It just takes one playdate for a runny-nosed neighbor to contaminate your child's toys, and from there, your whole household is at risk. So clean up those toys—at least, when the toys are Legos. These plastic bricks will easily survive a trip through the dishwasher, and it's much easier than disinfecting them one by one. Before their session, make sure they'll stay put by placing them in a mesh bag or other container that fits on the top rack.
