Crate Training a Dachshund Puppy

I have been trying to crate train my 9 week old Dachshund puppy. I got him Friday and he does like his crate. He goes in and out without any problem but as soon as I put him in there for a nap or bedtime he freaks out and whines and chews at the bars. I leave him in there for school and I don’t know if he settles or not. When I come home he whines but I think it is cause he hears me come in. Any tips? I end up just letting in my bed at night cause he only settles for like 1 a hour or 2. I need some sleep for school and he sleeps just fine in my bed.
