Stimulation of the senses can be very important with toddlers. The senses are being stimulated. Just seeing some things can take care of this stimulation. Little children want to touch some different materials and textures to get to know how this feels and if they like it or not. This is important, because when the toddlers don't get a chance of feeling and sense stimulation, they can get depressed and there can follow an inactivity. 

The stimulation of the sense can happen with the hands, but also by using the feet. Using a barefoot path can stimulate the sense with the toddler and the parents, because they are feeling different kinds of materials under their feet. This can enlarge the resistance of the parents and their toddler. It also can stimulate the fact that they would get some self confidence.
