Run around or be carried- that is the question

One toddler issue- run or be carried.  This little guy is very happy running around "chasing" his Mom, until he is done and ready to be carried. Soon, he will want to get down and run again. This can be very frustrating for parents who are trying to get some place or who want the kid to get some exercise.  Often, everybody is happy if you can switch between running and carrying- real often.
