Built a treehouse with my boys this summer
Started this project with my 8 and 10 year old back in June. Had no idea what I was doing honestly but I found some plans online and we went to it. My wife thought I was crazy but the boys were so excited. Took us about 6 weeks of weekends but we finally finished it last month. Best part is watching them play up there with their friends now. They built something with their own hands and it's solid. Thinking about documenting it better for my younger kids to do later.
This is the kind of project that bonds kids and parents. They learned problem solving, got to be outside, and spent real time with you. Way better than any store bought toy.
