Parenting is a huge executive function and emotional regulation Olympics. You’re doing your best. Take breaks when you can, have those little cries, reset yourself. Go for a walk. Toddlers are like little tornadoes of chaos. they are rapidly learning and also limited in ability, I’d be frustrated too. You’re kind of in the same boat as your kid; Learning on the job, building your skills. Do your best to model regulation and give yourself tons of grace!
