DS developed a fear of cot?

[Fcas]

DS is 11m now and fir the past week or so, everytime I go to lay him down in his cot (previously no problem at all) he cries hysterically.
I can not pin point an exact time this started or any changes or events.
I have tried rocking him to sleep then laying him in and as soon as his head hits the mattress he jumps up.
I have tried co-sleeping then moving him across to his cot when he is in a deep sleep, but he wakes again.

Has anyone else had a similar experience?

he's realised that you Go Away, so the crying is a response to that

can you co sleep safely all the time, keep him close and comforted?

Well that is what I am doing with him at the moment. I just dont like to leave him in our bed on his own, so its a case of when he goes to sleep at 7pm I either hold him in my arms until i'm ready to go to bed or lay beside him.
He is walking and climbing and thinks nothing of climbing out of our bed.. Which is fine when I am there, but I dont like the idea of him falling, when hes half asleep and me not hearing on the monitor.
He would probably climb fine.. And I would hear him on the monitor, But its a 'what if' situation.

Ds had a genuine issue with her cot at around that age. We ended up putting her mattress on the floor for a night and that was it, out like a light. If someone had told me that story I would never have believed them, a child of that age having an issue like that but mine absolutely did.

DS has a cotbed, so was thinking of dropping the bars?

Between 9 and 12 months babies develop attachment anxiety. He has suddenly realised that you go away but has not yet learned that you will come back so cries because he thinks you have left him. My health visitor advised a strategy that teaches the baby that you are still there even when they cant see you. With my dd we put her in her cot, kiss her and then go out of the room. After one minute we go back in and lay her down again. We repeat this - leaving her no longer than one minute until she finally gives in and goes to sleep. What this teaches my daughter is that mummy is still here, she isn't gone, but it is time for bed. The first night it took about 2 hours, then within a week she was laying down and sleeping within 5 minutes. With my daughter, staying in the room just fuelled her crying. She would stand up and scream at me an then as we lay her down she would twist and kick which made it very hard. A couple of times she was even sick. Bringing her into my own bed led to more screaming, twisting around and escaping off the bed! The problem was she was tired so she would scream and scream. Once I implemented the strategy that my HV had suggested she was much better. I do not agree with leaving a baby to cry ever. However, I have learned with my own child that I have to allow her to express her frustration and teach her to calm down. Good luck xx

That is really helpful, thank you.
I have been in the exact same position with DS he cries screams and throws himself about in the cot. So I will definatly be giving this a go.

I read all these different discussions, and tactics to get babies to sleep and just assume they wont work with my DS!
Hes very stubborn!

The first couple of nights are really tough but it soon settles down I promise. I forgot to add above, when I go back into her I dont talk to her, I just repeat the laying down process. Now we have her fairly well trained it is really funny to listen to her babbling her frustrations on the baby monitor, she isnt crying, just chatting but it sounds like she is telling me off! Usually she falls asleep quite quickly once she has had her chatty rant! x
