Puppy training HELP!!?

A week ago I got a 2 month old puppy. They said she was a golden mix, but I am not sure. I have a 3 year old and the puppy is awfully nippy, I know she is just puppy playing but it is terrorizing my daughter. I have tried yelping, giving her a chew toy, etc. But nothing is seeming to make a difference. Can anyone recommend training tips? Or somewhere to take cles, we live in the Cleveland, Ohio area.
