Send help the nipping/ mouthing is so bad 😭😭

I have a 14 week old GSD and she’s a shark. I know it’s normal and part of growing up but I need help. I just don’t know how to get her to create a positive association with a toy instead of my arm/hand/ankle/pants. I’ve tried redirecting and she still goes for my hands instead. My partner and I give her so much attention that she has no reason to nip out of a want for attention and we commit to exercising her and giving her lots of mental stimulation daily that she can’t be nipping as a reason to tell us something she’s just nipping for fun at this point and it’s only getting worse (as in she’s getting stronger so it hurts more)

Please if you have any tips I’m open to trying them out also for some reassurance please let me know at what age did yours grow out of it 😭.

Attached is a pic of my sweet sweet gremlin just for fun.
