Built a treehouse with my kids this weekend and it was chaos

So I decided Saturday morning that we were building a treehouse. Didn't have plans drawn up or anything, just some 2x8s and a vague idea. My oldest helped me hoist the first platform and my youngest kept handing me nails he found in the garage. By hour 3 my wife was yelling that lunch was ready and we still didn't have railings. Took us most of Sunday but now the kids have their own little fortress. They've been in there all week. 10/10 would recommend, my back disagrees though.
