Traveling is a cost to your family, you need the other part of the equation. If there's no benefit then the answer should be hell no, because it can be a struggle. Is your wife an independent or dependent spouse? You don't have to give us that answer but you need to consider it, if she depends heavily on you then it could quickly come unraveled. Do you do everything together, or have separate hobbies, friends, etc? Kids are flexible and it will probably impact them less, especially if you make the effort to call, Facetime, Skype, etc. You'll just need to make up for the lack of attention when you are home.
