I take Simon and Hallie for a walk every morning (even when I don't want to get out of bed), every evening, and at lunch if they aren't at daycare.
We walk more on the weekends when I'm home and I'm going to start walking them further after the new year. The entire circle of my apartment complex is about 2 miles and right now we usually walk the mile.
Wish Hallie luck, she would rather stay at home in bed

haha
