As we said a few months ago, after another child – an 18-month old boy – died the same way, please:
Keep cots, beds and other furniture away from blind cords.
Keep cords out of reach, by winding them on a hook or clipping them to the blind.
Look out especially for older cords that are looped, or knotted or otherwise joined at the tassels. In most cases these can be made less dangerous by cutting the loop or the join, and fixing new tassels on the cut ends.
In some cases a blind might require a continuous loop of cord to work. These cords can be made less dangerous by keeping the loop taut through a cleat fixed to the floor or wall.
Cutting through cords and fixing cleats like this are alterations to the property, for which you should properly seek your landlord's consent. As minor alterations, your landlord cannot refuse consent unreasonably. And it is hard to think of any good reason for refusing consent for you to do these very simple things to make your home safer for children.
