This is one of the problems I find with some parents these days. They constantly entertain their child and feel that we must do the same. The child then doesn't learn how to free play. This is such an important part of a child's development. They need to use an imagination and be able to think for themselves. I have had a few like that although not to that extreme.

Your new favorite words should be "Go play". I also don't allow the kids in my space when preparing meals and if they ask what we are having I tell them they will find out when the time comes and to go play.

I think by you printing off worksheets it is just encouraging her to keep asking. You need to force her to think for herself by not doing for her. She needs the adults in her life to step back and let her explore on her own.
