How to not lose your cool when your child is melting down.

I want to preface this by saying I am dealing with PPD, PPA, and PPOCD. My mental health, even with everything that I try to do to help it, is in the dumps. I am struggling with it on a daily basis. I'm working with my PCP and a therapist to get it under control.I have an almost 3 year old that is out of control. If I put my foot down about something he screams and cries. If I let him do something he wants to do, he screams and cries. If I don't do something exactly right, he screams and cries. His 1 year old sister looks at him? Yep, he screams and cries.I get frustrated and fed up and become visibly frustrated with this day in and day out screaming. I don't know what to do. Every article I read about how to deal with tantrums says "keep your cool" but none of them tell you how.During my childhood keeping your cool was never modeled to me. My parents never kept their cool with me. I wasn't physically abused but I remember one time when I was probably 7, we had just gotten home fr church and I couldn't get my dress off and started panicking. I begged my mom to help me and she wouldn't. She was busy making lunch or something. Next thing I know she storms over to me and rips the dress over my head and throws it at me. It hurt like hell, that dress being ripped off over my head. That's the kind of modeling of parental behavior I had.I don't have the tools to figure this out myself so I'm here asking what tips you guys have. I need help. Please be kind. I don't want this cycle to continue in my family and I know it starts with me. via /r/Parenting https://ift.tt/31LRTes
