My computer's doing all sorts of funky stuff so we brought it in to be looked at on Saturday and I still don't have it back. Sigh. I do so miss my computer! Anyway, I wanted to share this video while I have the chance to jump on a computer for a few minutes. I gave the kids a design-your-own marble run for Christmas (very reduced price from Mindware) and B took it out today for the first time. I was amazed at his concentration while putting this together. He designed this marble run himself with just a little help from his Mama.
