Help...

Any idea on how to get my baby to take a nap in his crib. He sleeps in his crib at night, but won’t take a nap in it. He cry’s and cry’s and cry’s if I put him in there. It pisses him off to the point where I can’t even get him to take a nap in my bed where he usually takes one. Idk what to do anymore. I want him to take a nap in his crib.
