I just posted about the realization that, though I am natively fluent in Spanish, there were many words on which I needed a refresher. One of N’s first obsessions was with trucks, specifically those having to do with construction. My preferred way to learn more about them was through books (which you will notice is a common theme for me, just because they relieve so much of the pressure of providing new and interesting vocabulary), but along the way we’ve also encountered the occasional show and activity that spark some great opportunities for expanding their (and refreshing my) vocabulary.
Both N and E love this book, which their grandmother brought on a visit about a year ago and is still in our bedtime rotation.
