Our 2 year old transitioned to our bed. How do I get him back to his crib?

It all started about a month and a half ago when he developed a fear of bugs. He would wake up terrified in his crib, staring down at the mattress and just screaming until one of us picks him up and puts him in our bed. He even tells us 'scared of bugs' or 'bugs in crib'. We tried to explain to him many times that there aren't any bugs, and that he's safe there, but nope. I should mention that we live in a small place, therefore his crib is in our bedroom. Since then, I feel that the overall BUG fear has gone down, but his habit of waking up, screaming, demanding that we put him in our bed has worsened. We can't soothe him back to sleep, talk to him, nothing.... I'd love to nip this in the bud before it's too late, any advice is appreciated. via /r/Parenting http://ift.tt/2uw5XfB
