I love the outside at the end of the day because I only have to dress them once, no undressing and all the sand, dirt and grass goes home instead of back into my house. We go out after nap and stay out till pickup. Winter right now only the older ones are going out for awhile right after an early lunch and the little ones are already in bed. I watch from the door while they flop around for 15-20 minutes in the drifts and then they have had enough and come in.
