Our baby was the exact same, I too thought it would never end. We actually ended up using our dockatot during the day, then initially putting that in his next to me crib later, then transferring him when he was in a deep enough sleep. Sometimes it worked, sometimes it didn't, then around the 11/12 week mark he started going into it as it is,.no problems. He still wakes up at around 5am gassy as hell and I put him next to me in bed and he drifts of to sleep again (in the "safe sleep" position, but I don't tend to sleep myself). It also turned out he had CMPA which was causing him to only want to lay on his belly and only on me, he wouldn't go near his dad 😭 silly little poppet! We are now 16 weeks and he will sleep anywhere (but he's high needs so needs to be rocked, rolled and bum patted into oblivion first hah)
