Although it's easy to see improvements in large motor skills, one-year-olds are also improving their ability to use their hands and fingers, allowing them to examine objects and attempt new movements with greater precision. At this age, toddlers enjoy turning over containers to pour out their contents, building towers of blocks and knocking them down, turning pages, and scribbling. These activities aid the development of hand skills and help children grasp important spatial concepts ("in," "on," "under," and "around"). These new abilities also bring new opportunities to get into trouble, so making sure that dangerous items and materials are out of reach is important. It's a good idea to do a safety check on the environment to help prevent accidents.
