No one warned me about a six month sleep regression

I’ve had a great sleeper this whole time. Even as a newborn we’d get three hour stretches which is better than some I know. Sleeping 6+ hours consistently right before 3 months. Never had a 4 month sleep regression. But now? We’re getting 30 minute to an hour stretches. I don’t know how to cope 😩 I’ve seen him put himself back to sleep for months , we didn’t have an issue when teeth came in a month ago. Tell me this ends soon!
