Nagging child, should I punish?

My child follows me around the house lately and nags me. Lately, she has checked out comic books at the library. She wants to show me 50 comics in the latest book. She will not settle on me sitting down for a few at a time.

She followed me around with the book at the crack of dawn yesterday and I said I had to shower and couldn't read it yet. She waited until I got out of the shower and I said please, you know what nagging is at 11 years old. She wouldn't even let me get dressed. After I got dressed, she said "I know you don't like when I do that thing but can we read that thing now?"

Which was nagging again.

I told her no because she was nagging and trying to hide it.

A day later, she started up with the book right in my face again. I don't even have a chance to get my coffee. I have a very needy 11 year old and I don't know what to do about it. This is with the new Minecraft game, with letting her use my PC for chat rooms, she will beg and nag and I NEVER give in to her nagging. How do I make it stop?

If you didn't want to raise kids, why did you have them?

Get some rules. Set time for you and time for her. Say she can have two hours of your time and set the time. Stick to it. She will learn eventually

Why not bend a little and pander to her wants

Don't punish her just give her an hour or so Stop being selfish with your time She is wanting attention and found a way to get it. She is in desperate need of your time. Give it to her.
