Oh my goodness we went through the same thing with our little Bella! In my opinion we got her a little earlier (she was barely 7 weeks when we got her) then my comfort so we had a lot of separation crying. The first week was AWEFUL. She cried and cried and no matter what my husband and I did she wouldn't stop unless we let her sleep in bed with us. What I tried was having her follow me to outside of her crate and guiding her into the crate while saying "go to bed" then giving her a treat once she was inside. Eventually I'd close the door and praise her with a treat (if she wasn't crying). I did put an old tshirt in the crate to try and comfort her, but be careful with that. The best advice was given to me by a friend and she said "your dog doesn't know an old shirt from a new shirt, nor old shoes from expensive name brand heels." So when you give them an old shirt of yours, that ultimately gives them permission to have access to all your shirts.
Side note, putting the crate in the bedroom is a very very good idea. It allows your baby to be around you and be comforted by your presence without them laying in your bed. Just be patient with your little one. There are a couple angles to crate training so I'd read up on it. It just depends what your little one responds to the best.
