With the youngest munchkin showing a distinct interest in tools and building things we picked up a couple of erector sets at the store this weekend. We picked up a set for the kid, and since I had never had Erector sets before one for me as well.
I won’t know about smaller set until after Christmas, but my set is really complicated. It makes Lego looked like it was designed for toddlers. It’s actually more than I’m mentally prepared to take on at the moment. I’m not sure where they found an 8-year-old to attempt it, but I want that kid working on my car in a couple of years.
