She just loves prank calling I guess, she has done it previouslly and I took her phone and grounded her. She did it again so my punishment must not have worked. I have to do something different this time! Is she to old for spankings? Maybe... If she wants to act like a kid, I can put her in a good, long, boring timeout? But I really don't know what to do because grounding didn't work and I think she might be to old for timeouts and spanking. Parents please give me some advice on this one.
