I feel your pain, I have a 3 and 6 yo kids and they made it tough to get anything done, but I also had the bigger problem of my birds getting too big to keep in the garage any longer and I was forced to spend every free minute working on the coop. Still have a few odds and ends to do but for the most part it is done. I am sure I will always be tinkering with it. Like I plan to add another window this weekend and still need to add the nestboxes(have some time for that). Also needs painted still.
Hang in there it will get done.
