I have always frowned upon people who have their kids on leashes in theme parks or malls. But, now that I have a DS2 -I can understand. He likes to walk, is very energetic, tends to run off, etc.. My DD4 was never a problem. She loved being held and loved the stroller. I am debating about whether or not to get a leash for DS this coming trip. Any input? And do they sell them in the Disney parks for a reasonable price?
