My oldest, a boy, was about 3 and my daughter was 1 1/2. She was standing on a kitchen chair to reach something on the table. I told my son to get her down, of course envisioning him gently putting his arms around her waist and lifting her down. Nope. He grabbed her leg and pulled. I believe this is called obeying the letter of the law. lol
I learned to explain how to do things in more detail.
