I change kids garanteed 3 times a day but check inbetween for neccessary changes. Some kids only get changed the 3 times at the scheduled change time while others can get changed up to 6 times. It all depends on the kid. My scheduled change times are about 9:45 (after snack/before outside time), 12:30 (after lunch/before afternoon nap), and 3pm (after nap).
