Baby HATES his crib! How can I transition him?

Hey ladies,

So my son is 4 months old and we have tried several times to transition him to his crib from his bassinet. We put him down every night in there and he will sleep for maybe an hour at the most and then wake up screaming. I have tried everything!! I try to go in and comfort him, I tried leaving him for a bit to see if he can self sooth! I even tried sleeping on an air mattress in his room with him. Even during the day, he will not nap more than a half hour in his crib, but if I put him in the bassinet he will sleep for 1-2 hours!

We have a good mattress that is WAY better than his bassinet mattress and I tried different crib sheets to see if that is the issue.

My GP was freaking out over the fact that he is not fully transitioned into his crib yet and I know I need to stop caving with his bassinet but my husband’s work schedule changed and he now does 10 days in a row and 5 days off, so I’m basically on my own. I get so exhausted that I just give in sometimes! 😓

Has anyone else had this issue? Any advice would be greatly appreciated!
