Also there's a bit of cultural assumption going on here. Based on the amount of comments, the poster's child is probably a native English speaker. My nephew is not, and has only begun learning English in school.
If the goal is "Let's make something for my child" that's cool and needs no change. If the goal is "Let's make something to help children learn programming", a more difficult and noble goal, then removing barriers such as English fluency, is a way to do that.
