The main safety challenges for one-year-olds stem from their ability to move and their curiosity. During this year, your child's mobility will make it easier for him to reach and touch more objects than he used to. His increased speed and feelings of confidence make accidents more likely to occur than they were when he was being carried around. The good new is that accidents, especially serious ones, are often preventable. If you take appropriate precautions, you will ensure that your one-year-old will be able to happily and safely explore his world.
