Sleep regression? Clingy?

Gosh my sweet little boy has been waking up about every hour? Maybe every 2? Who even knows. He’s been sleeping in his cot since birth, with the exception of some of his night feeds, where if it takes too long, he’d end up sleeping on me until his next feed because I’d fall asleep 🙈.

He’s now going though this phase where he’ll sleep in his cot for about 1-2 hours, cry and then nurse for about 2 mins and then fall asleep.

So I now think he’s just waking up to comfort feed/co-sleep.

I don’t know what to do, and how to get him back to sleeping through the night in his cot.

If he has to wake up every 3 hours, that’s still fine, but I cannot do this 1-2 hour thing. It’s draining my life. Anyone else going thorough this or gone through it?

I’m considering letting him just lie in his cot and cry until he falls asleep because I’m not sure how else to address the problem. But I also feel like it’s a bit mean to do that 🙈
