I've got a 2.5 year old boy and a 4 month old boy, so my situation has been similar the past few years. I just accept that my hunting time will be limited for the next few years. I get out to archery hunt about one evening a week during season, and save a vacation day for the rifle opener. In a few years I'll have little guys tagging along with me sometimes, and when I do go out on my own they'll at least be potty trained and hopefully easier for my wife to manage alone.
