Our son (just turning 2years) was always a terrible sleeper, too sensitive, extremely alert. But what he's doing now is another level. I'm early stage of pregnancy with no 2 and both hubby and I are exhausted. We enrolled him to nursery 3 days a week a month ago and that's when his separation anxiety kicked off. He was panicking when I was about to leave the room after our milk, 2 books and lullaby routine. We tried the Ferber technique which usualy worked during each of his sleep regression. Well, this time he kept crying hysterically for 3.5h exhausted falling asleep for 20min standing up leaning over the cotbed only to wake up and cry again until we gave up, picked him up and started co-sleeping which we never wanted to do. He then demands co-sleeping during nap times so one of us always has to be in bed with him at 7.30pm and from 12-2am. It worked for a week but now he went another level up. After we finish bath, milk, books& lullaby in his room, I pick him up and carry him to my or dad's room (his choice is usually dad's room) where he throws massive tantrums ie he wants to sleep in guest bedroom with parent(then he doesnr), he wants to sleep on my face so I can't breath, he wants to go downstairs and play... he stands up right next to me in bed and cries for well over 3h until exhausted collaps down asleep. Putting him down and talking to him makes things worse. Best if we ignore him, lying down in bed and let him collaps eventually (nerv wrecking experience). He does the same if he co-sleep with the other parent and also during nap time. He is healthy, not thirsty and well fed, not teething. I dont know what more he wants. We tried to move him back to his cot in his bedroom and that went down terribly. He ended up back with us and keeps on to his 3h crying stints, usually from 1-4am or during bedtime 7.30-11pm. I'm typing this at 3.3am as our son cries for the past 3.5h non stop in the room with my husband. He doesnt want me, he made it clear he wants to sleep with dad and me to go away yet he cries for hours anyway. Is this some sort of sleep regression teamed up with separation anxiety and tantrums? Did anyone experience similarly disturbing sleeping patterns? How long it last? Will he eventually go back to his room or are we going to be like this for the next 2-3 years? I'm about to top myself.
