Go back to the basics.
Journal out or evaluate how you are doing in the following areas and take action where you can and need to:
Simplifying - are there areas that you could simplify or quiet things down enough to make a difference for your child?
Self Care - spend some time thinking about how you are doing with this. A great way to know is to ask your spouse or partner! Are you doing enough that it is building your window of tolerance? How about for your child? Are you building in enough time each day for them that THEY are able to build THEIR window of tolerance?
Are you pouring into your brain enough about parenting and trauma and the effects of trauma that when you are hit with a big behavior, you are able to stay in logic with it instead of becoming emotionally reactive?
Are you sticking with what you said you would stick with? For example, let’s say you wanted to tackle your child hurting you when they are frustrated. You picked the consequence - are you sticking with it?
Have you taken on too much? Trying to tackle too many behaviors and core issues at one time? Look at that and maybe scale back a bit so you don’t burn out!
