I walked into my son's room, and heard a video going. I looked to them amd saw ds on dh's lap with an open book in front of them that had a picture of a rocket.
The noise- was dh showing him a youtube video of a shuttle launch. Ds was really into it! "FLY, ROCKET! FLY!"
Great idea dada! :D
He's now running around saying, "big rocket fly! Leave planet!"
