How to run with new baby in the house?

So my wife and I had our second child last Thursday (Yay!!!!), and I haven't gone for a single run since then. I've been so exhausted with so little sleep, that I haven't been able to wake up for my normal 5am runs. Any other dads or moms with advice on how to squeeze in the runs while juggling a newborn and a toddler, but not take away from family time?
