I feel at my breaking point my 3.5 year olds out of control. She doesn't give a Shit and doesn t listen at all. I can punish her and she will just walk off like nothing and move on to something else she isn't supposed to be doing instantly. She's constantly throwing toys and other objects at her siblings really hurting them. And if it's not throwing stuff she s hitting and pinching etc. It's recently just gotten really bad over last month but it's just progressing. School is bout to start again and I'm worried she will act this way and get kicked out of preschool. Idk what to do ..i keep crying cuz I feel like I'm failing like I'm doing something wrong...but I can't seem to get thru to her
