I think with age they may grow out of it...and who knows, you maybe become like me and start following them......
I'm still waiting for mine to grow out of a whole list of stuff. Some she has, some she hasn't.

I have one of each kind of kid. My toddler is extraordinarily good at keeping herself entertained, and since she worked out how to open the fridge, the back door and the car she barely needs us at all. Her catchcry at the moment is "NO. I doing it by MYSELF" and you know about it if you invade her personal space or worse, try and help her with something. Miss Independant eat your heart out.

Other one (who is almost TEN) is constantly bored and alarmingly bad at keeping herself entertained. She needs to be around people all the time. If she does play alone she has to show you what she's doing every few minutes (yes, I timed, she's better now but she used to not be able to stick with anything without talking for more than 7 minutes), or at the very least she has to be within shouting distance of you so she can shout what she's doing. It drives me completely bonkers that she can't even watch TV by herself without yelling about it constantly. She can't even read a book without telling us what is happening in it. Fortunately she has discovered we live about a block from several of her friends so she visits them a lot, and of course she's in school most of the time. I'm really looking forward to her hitting puberty and starting to keep secrets, although with her past track record I have a feeling I'm going to get the blow by blow minutea of everything she does with boys.

The baby doesn't count in this discussion, he's a 3 months old velcro baby and he's only happy if the milk bar is within his sight
