Oh poor baby! Bless you and your family for taking her in. Now since you said it's more nibbling, I think that she's not being mean per say, but it's basically her way of showing affection.
I know Gizmo when he's happy to see us in the morning, he comes up to my husband and I and nibbles on our ears.
Also, you have to remember this poor baby has been bopped back and forth. And to be honest, for having her for only a few weeks and just nibbling is the only problem you're experiencing, then you guys are doing really good!
When Gizmo nibbles too hard on either one of us, we make a high pitched noise turn away from him and don't engage him for about 30 seconds. He doesn't like the lack of attention and learned pretty quickly. However, that still doesn't change his ear nibbling morning routine, but he knows not to nibble hard.
Hopefully this helps. Like I said, you've had her for a few weeks, so she's going to be "testing the water" so-to-speak with how you react to things. I'm thinking the nibbling on your daughters tootsies is her being happy to see you come home.
Keep us updated! And good luck!
