Bumbly, you have my total sympathies. You're really not alone in this.
It's awful. It's so hard. You feel like the child is in control of the day, your marriage and your home.
My DS has been raging for 2 years plus now (he's nearly four) - at least twice every day - and every weekend is strained, stressed and full of upset for everyone.
Of course, he's an angel at nursery or with relatives so nobody believes us how bad it can be.
We just can't handle it either. We've tried everything from talking to him, hugging, hugging him in a darkened room to calm him, ignoring, taking toys away, distracting.
When he's in a fury, it seems we cannot get through to him. And he is expert at divide and rule over DH and I. We're suckers for that and it's affecting our relationship.
One thing that did seem to work for a while was sitting him on the step "to think about what you're doing," but I think your LO is too young for that.
Sorry not to be more constructive.
