Crate Training With A Blanket?

I recently got a 10 week old Cockapoo and made the mistake of letting him sleep with me instead of in his crate. Well, I realized that when I’m staying with a friend for a week, he won’t be able to, so I decided to make him sleep in his crate. When I put him in his crate, he whines SO much. I know I’m supposed to just let him whine, but I can’t! So, I put a blanket over the crate and he hasn’t whined at all! Is there anything wrong with doing this? I know this is the stupidest question, but this is my first dog so I don’t know all of the tricks Thanks a lot!
