Co-sleeping

We started co-sleeping with our son when he was about a week old because that’s the only way he’d sleep. He’s now turning 8 months old at the end of the month and my husband stays he’s too young to sleep in his own bed. I’m so exhausted and don’t sleep well because this kids is ALL over the place.

My husband did what ever parent SHOULDN’T do and got spooked by the lovely internet. Has anyone else gone through this? How can we transition him to his own bed before it’s too late?
