I have the same problem with my 4 month old princess Jackie.
She bites a lot (especially feet) and when I'm in a hurry (going for work), that can get really frustrating.
She responds very well on redirecting her. I say "stop it" and if she does not stop i pull her away and give her the toy. It kinda works, i can see improvements ... now when i say "stop it" she sometimes grabs the toy and goes away.
I recently bought her something to chew as well ... it's some kinds of raw/dried skin (completely natural) and she can chew that for hours. But this is not about redirecting her ... i noticed that she bites less and less! It's like she wastes her 'biting energy' on that skin and she doesn't bite feed anymore.
It's just a suggestion. That worked for me.
