That's every father's worst nightmare... well, maybe not the worst. But the most innocent one out of the worst. I wouldn't worry about it yet. Just don't get her any toy phones or anything like a phone that is a toy.
Aw, she's adorable! My niece is up and walking, and she's not even one yet. I guess she's a handful for my brother. She's always running around the house and causing havoc. Glad to hear your daughter's doing well. Gotta get her working on "dada"
