The only reason this would worry me is a) when it comes time for her to start school, I have heard some absolute horror stories about kids who are very smart and are super-bored who become disruptive or are just generally energetic kids, their teachers can't/won't deal with them and demand that they be diagnosed as ADD and medicated, even if they're not...
Cross that bridge when you come to it (and you prolly wont), you have plenty of things to stress about at present. Don't stress.

But darl, you can't expect an energetic toddler to listen to NO. You have to remove them from the situation or remove the problem. The ain't gonna listen when you tell them not to do something fun!
