Anyone have a younger child very attached to an older child?

I really don't know how to tell you to handle it. Both of my girls are very attached to each other and miss each other terribly if they are apart. One is 0 and the other is 16 and they get along great for the most part. As you said though, the older one sometimes sees the younger one as a pest and needs a break. However, I don't see that the other way. The oldest one has even been mad if I let the younger one go spend the night with grandma because she isn't home with her. My two even sleep in the same room even though they have seperate rooms, because they don't want to be apart. I am sure the older one is going to want this to end soon and I am not sure how I will handle that either. It is nice that siblings are close and want to be with each other but it can almost be as bad as them fighting all the time too. Don't you agree?

You see how my sister's girls are. When they had separate rooms, they would end up in the same bed. So she moved them into the same room, separate beds and the same thing happened, they ended up in the same bed. She actually moved their beds together about a month ago so they would go to sleep. They seem to want to be together all the time. But then once in a while, the older one will just want to be alone and the little one just can't seem to be by herself. Is there anything Chandler likes to do alone, without JP? Maybe when JP wants to be alone, you can do something special with Chandler.
