Why is this so hard? I found myself doing this to my grown daughter the other day: “I will just interrupt you now and tell you the right answer.” Guess what? I wasn’t helpful, or even right! Damn.
I deal with young decider interns all the time, aged 2-5. There is a time to teach: “this is how to hold a hammer, please wear these goggles to protect your eyes. Friends, please move back while he uses the hammer.” and a time to ask wondering questions. “I wonder what you can use to do that?”
They will respect your input more if you respect their process more.
And, if you really wonder, you might see something that will tell you a lot about a child, or that may help you see a gap in their understanding. In fact, you may learn something!
