What type of flooring should a high traffic playroom for young children have

Personally I think it should have wood floors, young children tend to spill things. If you put down rug flooring then it will most likely get stains in it faster, whereas you can wipe spills up on wood better. Linoleum might also be another option, it's easy to put down, and it's relatively cheap. You can always add a throw rug on the ground to prevent falling on the "slick" floor.

i believe the answer would be negative peer pressure
