He would get so excited to push the button at the pelican crossing, wait for the red man to "go downstairs and change to green" then cross safely. He knows that even though the green man has appeared, he stills needs to look both ways in case any cars are still driving.
Now that he's four, he is much more independent so (mostly when we are near our house) I let him walk on ahead a little bit if we aren't near a busy road. He automatically stops at the edge of every pavement and waits for myself and his daddy to catch up. When next to him, we reinforce the "stop, look and listen" rule but to be honest, I think it's something that we need to work on as he does it a little half-heartedly so I'm not sure he's really taking his surroundings in. Luckily, he does always wait so we can teach him more about the importance.
How early did you/will you start talking to your children about road safety?
