Imagination

Noah has a great imagination! He is often scooping the air with his arm and he will tell me his is an excavator, or a backhoe. The other day he was looking for his little snow plow vehicle and he couldn't find it, so I told him to go and get one of the other cars and pretend it was a snow plow. So he went and got a regular old race car, and was able to go along with the story he was making up, pretending it was a snow plow. The big question for me is how to teach him the benefits of pretending / telling stories / using his imagination, and at the same time the importance of always telling the truth. How fun it is to be a mommy.
