“What is this called?”
There are so, so many things we parents do not know. This is a complicated time wherein there are some things we CANNOT know. The questions that are answerable are a no-brainer. Look it up. Find an expert. Ask Google.
Remember Middle School science class? where we learned The Scientific Method? Introducing the world to your child has a lot to do with modeling an approach to everything with that sort of strategy – question, research, hypothesis, experiment, conclusion, report, new questions (begin again!)
In finding something out together, you’ve taught even more than the singular fact. Your shared inquiry is shared learning, shared memory, shared wisdom. This is awesome parenting!
