Check out this horrendous video of a parent making their 3 year old little girl adjust the parking brake on a 2008 Jeep Grand Cherokee.
I don’t care how bad you want your daughter to be a mechanic, she is just too young to be handling this type of equipment! Always use your best judgement when put in a situation like this. She has plenty of time to gain learning experiences, and being three years old isn’t the right time!
