Ok so my DH has put the cot back up tonight and we're still having exactly the same issue 🤦🏼♀️
You will still have the same issue, because you've not solved anything (Just stopped there being loads of extra issues).
Sleep often goes rubbish at around 18 months, so this is where you are. I'm guessing baby is standing up in the cot and stood screaming to exhaustion? (This is typical for the 18m sleep regression). It's to do with motor skill development.
So to start, can baby go from standing to sitting to lying down totally unaided unaided? Assuming yes, start with instruction following games during the day.
Very basic things without lots of language attached, just clear instruction. "Can you stand up ?" Climb up on the sofa, take this into the kitchen, bring me the ball, touch your nose, sit down, stand up, lie down. Much like Simon Says buy without the Simon Says buy, just instruction and the lots of cheering when the instruction is followed.
Next, stop lying baby down in the cot (entirely, never do it again). Indeed stop doing anything for baby that he could do himself, show him how much praise he gets when following an instruction.
Put him in the cot stood up, tap the mattress and say lie down. Make a big fuss with smiling and praise when he follows the instruction.
He may (will) stand up. Just tap matters and give instruction again, waiting without getting cross of frustrated. Just keep repeating and waiting. Then praise when instruction us followed.
Bear in mind here that the only instruction is lie down. We cannot make him sleep, but we can (and will) insist he lies down. Don't complicate the battle with extra language or instruction. Just tap mattress, say lie down, wait, praise.
Once you've sorted lying down - next instruction is lie still and quietly. So have a mantra that you repeat. A clear sentence that sets out exactly what you expect. Ie "It's sleep time now. Lie down quietly to sleep. Nan night".
Then it comes down to being totally calm and consistent. Stay in the room, stay calm and don't get annoyed. But do not deviate from your expectations.
- kiss/cuddle
- into cot stood up
- tap mattress and say lie down.
- Smile and have positive body language when instructions followed. Bend down close to his face, say mantra
- "It's sleep time now. Lie down quietly to sleep. Nan night"
- stand and step away from the cot and wait.
- if he stands up, tap mattress and go from there repeating as above. Stay positive with every instruction followed
- if he is thrashing around or making noise, back over to cot and bend low, with a calm smile (He's lying down, that's good) put hand on chest with a shushhhhh. Then repeat mantra and go from there, repeating as above.
- if refusing to lie down or stop crying, pick up and go tight back to the kiss/cuddle in your arms as you did at the start it my bedtime. So kiss/cuddle until calm and start again, exactly the same.
You may need to repeat this whole process over and over and over and over and over again. Many many many times. But be consistent.
Say in the room until he's properly settle, then leave but initially wait by the door. Again if he stands or whatever, back to the above list to resettle in exactly the same way. And again once settled step away and wait by the door.
It's all about consistency.
