Rule I inherited from my mother: Children can climb trees as high as they can without help. If you need help to get up, you will most likely have trouble getting down.
Young T: Mom, may you help me climb the tree? (said with a two year-old accent.)
Me: No, I don't help little boys climb high.
Young T: Mom, may you help me climb low?
Me: No, if you can't climb by yourself you have to wait until you are bigger.
(repeat a time or two.)
Young T disappears into the house for a minute.
Young T: Mom, may I bring the step-stool outside?
At least he asked.
