Baby won't sleep away from me! Help!!!

(My son is 11 months old, 12 in December, single parent living at parents for some context) I'm gonna loose my God damn mind I used to co-sleep with my son for only the first few months of his life. I had to move back in with my parents and he's just gotten progressively worse. Especially cause they aren't strict at ALL!So my parents if they watch him for the night let him sleep in their bed in his own lil pillowed off area between em. Loves itWhen he slept next to me he's lay against the wall and my bed and would have about half the bed to himself. Loved it But mainly in his bassinet. Also loved that(yes I know what some parents are gonna say, co-sleeping in dangerous, pillows are dangerous blah blah blah. He's 11 months now, almost can walk. He never had any issues, any concerns nor did his pediatrician when I showed him photos if his sleep setup. And it was actually beneficial for bonding and monitoring especially with him being in NICU and had to be so closely monitored all the time once he got home)Around 8months he was getting WAY to big for his bassinet i wanted him to sleep in a crib, got his crib ready. (I tried every now and then for naps or a safe place for him to be but it was never routinely)He. REFUSES. TO. SLEEP. IN. IT. He won't go to bed on his own in it, he will wake up from the deepest of sleeps if I put him in it. He won't let me sing and talk to him until he falls asleep in it. Nothing. Nada. he just doesn't like it. Even though it's just across from my bed!He would only sleep in his swing that rocks back and forth. Out of desperation I let him, now he wont even sleep in that. ONLY NEXT TO ME. We share a room so we already have very limited space and privacy but COME. ON!Now I'd love to do the CIO Meathod, but he will literally cry and choke himself to the point he vomits, and because he's done that several times now. He won't even let me leave the room to pee, let alone even walk away from him before he starts profusely screaming. Even if he is safe, entertained, happy or whatever, the second I turn around he thinks I'm abandoning him an never returning. I'm at my wits end, how the hell do I get him to sleep in his own crib. What do I do?! I get maybe 1-3 hours of sleep now and I can't keep doing this. via /r/Parenting https://ift.tt/3CNHh1L
