Walking to the park today we passed a child that DS1 goes to school with and his younger sister who were walking back from the park alone. Their houSe is approx 5 mins walk from the park...there were no parents in sight! It is not the first time that I have seen the boy at the park alone but can't believe they would let him also take the little one with him. We live in a small (ish) town which is generally quite safe but am I being unreasonable and unnecessarily paranoid to think that children this young should not be left to go to the park alone???
