Needing help with toddler behavior

Harley

In need of help on how to control his behavior he's constantly doing stuff that can get him hurt even though me and his dad try to stop him. We have literally tried everything we can think of and don't want to bust his butt I have even asked his pediatrician for advice on how to go about getting him to stop but nothing works. Does anyone have any advice on how to get this to stop cause I'm ready to pull my hair out? 🤦
