How often do you allow your kids to play outdoors?

As much as i can, as i am working with my inlaws, making us to be at work almost everyday. I hardly have the time to bring my boys out. I almost made sure i let my younger son (1yo) to have some morning sun before we leave for work together. I will try to make time out every weekend for at least 1 hour of outdoor play for my elder son. so he can have his share of sweaty fun
