I found these old pictures and mostly wanted to upload them for posterity.
About this creation
Jules was two here. They obviously aren't the best models (even for Duplo), but we have so few pictures of the stuff we did back then...
Nicholas' Responses to Comments:
To Kathleen -- Thanks for the comment. I had heard that some people are using "LEGO Therapy" to help older children with autism, but I hadn't heard anything specifically about using DuploŽ with preschoolers. As someone who really loves LEGO and loves kids too, it makes me very happy to know that this can be of help. I'd love to hear back from you sometime about how it is going. And if we can help, for instance by making a specific model, let me know. I know regular LEGO gets most of the attention around here, but I am a true fan of both.
