Advice / reporting someone to Dss etc

So I’ve held off on reporting a specific person to dss, because I know calling Dss on someone is a pretty big deal. I don’t think it’s something that someone should catch them doing often or for small reasons. After everything I know, and have heard ( with some evidence of things here and there I could use to send in as well ) I feel that calling dss would be the right thing to do. BUT for some reason I feel like what I’m doing is wrong or not right, although I KNOW I’m not wrong for making a report. A girl I know has really no business raising kids. Last year she called me while drunk to tell me she’d slit my 4 year olds throat. There’s a video she posted on snap of her smoking a joint or blunt in her babies face. She doesn’t smoke cigarettes but she is a heavy weed user ( which I’m not against but in the babies face / in the same room as your kids..? ) there’s a voice recording I have of her kids aunt telling me about how the other day they got into it and the girl threw her car in reverse while her kid ( 8 ) was half in and half out of the car. Like he was getting in, hadn’t got in fully yet / or sat down and she throws her Car in reverse sticking her tongue out at his aunt who she was fighting with. She could have ran him over.. she stays drunk, she’s posted two separate posts on Facebook on how her man gets drunk and beats her and posts pictures of her face and she just takes him back. I have screenshots of her youngest kid ( 3 ) riding down the road in the back seat no car seat and not buckled. Screenshots of her youngest kids grandma on messenger talking about how her kids are traunt because she stays drunk and that on Christmas eve she locked her oldest son outside in the cold while she hit her bf ( they was drunk ) while he was holding their 2 year old etc. screenshots of her saying her sons daycare contacted dss because they found a grinder in his backpack.. she also left her baby in bed alone one night while he was asleep to chase down her bf they was fighting and drunk. She left the baby and took off chasing him in her car and crashed into a tree hut dss didn’t find out or get involved ( I don’t have proof of this I just know this from being told about it in person and saw pics of her car ) and then pics of her toddler on Halloween with a huge bong right behind his head. Also a screenshot of a post her boyfriend made the night they was fighting saying she was hitting him in his sleep and pulled a knife on him. The kids see and hear so much. That’s just what I know, the thought of what’s happened that I don’t know about is scary to me. Why do I feel like reporting her is wrong? She crashed out in her car one night after a party drunk and her son was in the back seat ( 2 ) her mom didn’t know where either of them was rode around and found her car parked with her two year old sitting in the back awake watching an iPad eating old chips so the mom just took him and went to feed him and never woke her up. She woke up and saw he was gone and called her mom crying saying he was missing but that’s when her mom told her she got him. I don’t have proof of that either, but something has got to give. This is all just considered neglect to me and I feel a report should be made.
