Jack is 22 months, and last week, after his dad got home from work, Robert (8) went out to play with the neighbour's child. The house went quiet shortly afterwards, I assumed Jack was with his dad and his dad assumed the same.
There was a knock at our door, and it was the neighbour returning Jack. He walked into her house, the same house his brother was in. But we live in the country, so the house is not just next door, but it's not too far away either. I now keep the doors locked.
SO children can get out very easily, just glad my child and this other child were safe, and glad his dog was looking after him.
