Looking for a bit of advice. My street is a real hot spot for flytipping and today's offering was a heap of manky, filthy mattresses and two pieces of a broken down bed frame with wood and nails exposed. I noted all the details so I could report it to the council. As the afternoon progressed I heard children's voices and saw two little boys, each with a football, running around by the flytip and then jumping and climbing on the filthy mattresses and using them as a launch pad to leap onto the broken bed frames. No adults around. They looked very young, about 5/6 years old. I was so worried about the risk to them that I opened my door and spoke to them, told them the mattresses were very dirty and "full of germs" (the stains were visible) and that they could hurt themselves on the bedframes. They picked up the footballs and trotted off, then as darkness fell they were back again, more jumping, chasing the footballs into the road and dodging cars so I chatted to them again.By talking to them I found out they are both in year 3 at the local primary school at the end of the street and that they live another street away. They looked younger than they are, very slight build for their age. I spoke gently to them, told then they could easily have an accident and also not to go running in the road after their footballs. The incident keeps preying on my mind, they could have had a fall or got run over. I can't think of anything else I could have done, and indeed am wondering if I overstepped the mark by twice telling them not to play in the rubbish. Wondering what others might have done?
