Just to clarify though that I do this when we are on outings and not here in our enclosed yard...two very different environments. I can let them do whatever when we are here and I certainly don't need to hover because I've set up the yard so it's very safe. But when I'm at the park, I do feel the need to watch pretty closely. I guess it also depends on what kind of structures you have in your neighborhood park and if you are lucky to have one with a play structure suitable for toddlers but in my case the structures are more for big kids so I do need to be "on"....especial ly because my current 18 month old is a total handful and I'm honestly starting to find he is taking FOREVER to mature...still always getting into everything, doesn't seem to understand "no" and still puts EVERYTHING in his mouth...I guess it depends on the child!
