As long as you're busy making robots while you're watching Robots.
George has always echoed and acted out scenes from the videos he watches. But I've noticed lately that he wants physical props. So, we pull out the Lego airplane when he's watching his airplane documentaries; play with the wind up submarine in the bathtub after watching boat documentaries; and this morning, we made several robots out of Tinkertoys while watching Robots. So much creativity going on around here lately, I love it!
Note to grandparents wondering what to get George for his birthday: We need more Tinkertoys!
