It's fun having kids, my 5th one just turned 10mos a few weeks ago, congrats. But with the system thing, I am compelled to tell you PS4 because I have one and that makes me bias towards it. I would go with Xbox One if you have 360, it's what you are use to and you can upgrade your Destiny account and not start over(that would suck). Anyways have a good one and enjoy being a father, nothing in the world like it.
