seeking a postive behavior coach for parents of for 4 year old
We have an active 4 year old boy who has been testing boundaries a lot over the past year or so. We are seeking a parent coach / behaviorist -- ideally someone who can work with us to better understand his behavior and put together a positive behavior plan for us to implement. He doesn’t seem to respond well to consequences — e.g. taking things away at home, but does better with things like giving space and opportunity to apologize. In sum, it seems a positive approach with incentives etc is likely going to be most effective, but we are worried we are too permissive and inconsistent, hence our request for help and structure. (Also, he seems to have much less of this behavior at school, it's mostly at home with us.)
Any recommendations for a fantastic coach/behaviorist is appreciated!
Thank you :)
