Up until now my lb has had a great routine and has slept well for 2x day naps and at night. Just before he turned 1 he started showing signs of separation anxiety and he starts screaming the minute we put him in the cot and try to leave the room mostly at night. I've tried shush pat, pick up/put down but he very quickly gets hysterical the minute I stop rubbing his back or move to set him down again. If I'm sitting in the room not making eye contact he just throws his dummy or toys to try to get my attention, then gets frustrated and cries. We're now having to hold and rock him until he's so tired he eventually falls asleep on us (this takes up to 4 hrs every night!) It feels like this has become the 'new routine' but I've no idea how to break it. We're at our wits end
