German Shepherd Puppy

Hi everyone! I just got a GSP about a week ago. She is 8 weeks old. I never had a dog in my life. And deep down im really scare. I have 3 kids, toddler twins and girl. My first day I was clueless until my coworker explained crate training. Makes soo much sense. She has had only 1 accident She ia like 90% on the wee wee pad the other times its the corner and misses but i consider it a victory bc she knows her area.

But biting. Omg how can i control that? My twins love her but she loves thier legs

If i yelp she stops and trys to lick me which im like okay are you getting this a no?

Training and socialuzation tips please im alllll for it

Im commited to give her a wonderful positive enviroment

I know i have some puppy blues bc its alot But i keep saying this will pass My hard work will pay off but i just need guidance
