Yes...there are leashes for children, but if you raise them right from the start you won't ever need them!
Irresposible parents....oh how I despise them. Other treats I have witnessed:
*leaving kids alone in the car
*having kids in the car without seatbelts on
*letting kids wander around while parents do their shopping
*parents who leave their kids alone in a shopping cart/on a bench/in the washroom
Just like some pet owners need training before bringing home a pet, some parents should take training courses before they can reproduce.
