13 month old won’t stay settled in cot

[Crackers1288]

Hi.
My Ds is 13 months old. Up until a year he was a good sleeper, He would have his last bottle and straight to sleep on one of us between 8-9pm and then we would transfer him to his cot where he would stay until 7-8 am.
He would wake maybe once but dummy in and white noise on and a pat on the bum and he would settle straight back to sleep.

Since he turned one this has all gone out of the window and he will have his last bottle and fall asleep still but he wakes up crying his eyes out a few times a night.
He won’t settle back to sleep unless one of us takes him into the bed.
We think this was due to teething as his back teeth have been coming through.

I know we have probably made the problem worse by taking him in with us but it’s the only way we could get any sleep.
I’m at work three nights a week and the nights that I am at home dp is up early on those mornings so sleep training will be hard to implement.

Just asking for some advice really. Is sleep training the only way to go and should we just suck it up for a couple of weeks or does anyone have any other suggestions?

Thank you for reading

I think maybe he's older now he's just more aware of the fact that you're not there, and that's the only way he knows how to go to sleep.
Someone once said to me, if you fall asleep in your bed but wake up in the garden with no memory of getting there, you'd understandably be distressed. So perhaps it's the same for him - falls asleep on comfy parent, wakes up alone in his cot.

Hi thanks for your reply. Yes that makes complete sense!

We started to put him in our double bed after his bottle and he was self settling in that bed... obviously we weaker watching him on the monitor...
So it’s just his cot that e doesn’t seem to get on with!
It’s strange but we’re just going to get through it until he’s old enough for his own ‘big’ bed.
