I hate to say my kids have toy phones and want nothing to do with them - they want the real thing, so for us the toy phones are a waste of space. You shouldn't stop her talking to her grandparents that's great. It's all a learning process for her, and you just need to set boundaries. Tell her she can't pick up the phone herself, and can only talk when you say. It's normal for them to want to talk to whom ever you are, but you need to be firm. Does she nap or play independently during the day, so you can make important calls? Can you go into another room, knowing she is safe, so you have quiet on the call. I'm not saying hide away, but when I need to call companies that keep you waiting 10mins, the last thing I want is to be cut off by my 2 year old, and have to go back in the line! We are going through this at the moment with our 2 year old. I answer one phone and he goes to another and picks it up - I guess the heavy breathing and giggling isn't coming from my caller! Distract her with activities while you are on the phone. Good luck, we take it for granted all the things we need to teach our kid, and the things they need to learn!
