It sounds to me like you have a normal loving baby girl. I am guessing that this is your 1st PB(or mix) they are spunky little critters. That is one of thing that I love about them, push me and I'll push you back. My girl is an American Bulldog and she can dish it out, as well as, take it. If your husband plays rough with her, he can expect her to be rough back. Their tenacity/strength is one of the things that make them great with kids. My girl is gentle as a kitten with children, but she will rough house like all helk with me. They are powerful dogs and can handle with ease the abuse that comes with being around children (eye polks, tail pulls, ear pulling, etc) You just need to teach her that it is unacceptable to use her mouth in any situation (that goes for all puppies of any breed) and you will be fine. Even though she sounds stable healthy and happy never leave her alone with the baby they can play rough, and the rough housing may hurt the baby. Teach your girl some manners and you should be fine.
