Night times

My lb is 7months and sleeps an easy 3hrs when he first goes down around 7:30 and self settles for this pretty easy. He always wakes for a bottle around 10:30 - 11 I’m finding after this it’s so hard to get him to settle back in his cot! Just wakes constantly.. sometimes just after 10mins - maximum 1 hour and won’t self settle back off usually resulting in me giving up after multiple failed attempts and us co sleeping. I’m now back at work and I really wanna get him back into his cot as I struggle to have a good nights sleep with him in with me. It’s almost like he knows this is the time I go to bed so refuses to settle unless he’s with me. He always used to be a good cot sleeper but since teething has hit it’s all gone to pot! (We’re now over this) but will not stay in his cot! Any advice I’d be so grateful - super tired mama here 😴
