Unfortunately aggression can come with the territory. My advice as the mother of an aggressive child is this:
1) Keep a notebook for recording the episodes. Write down what happened right before, aggressive behavior that occurred, how long it lasted, and how it stopped or was redirected. Over time this will help you figure out her triggers for the behaviors. Also this is helpful information for a professional if you are seeking help so they can analyze the information and get a good picture of what happens.
2. Avoid saying "no". Instead maybe you can say, "not right now", or "maybe later" or "yes, we can do that at 3:00."
3. If she is not fully verbal a picture schedule might be a good idea. This way she knows what to expect and when. Sometimes not knowing what is going to happen before it does can be a trigger for aggressive behaviors as a defense mechanism.
4. If you can see signs of the episode beginning, have your other child go to a safer area, or get her to an area with little to no glass or possible projectiles. In this way you keep damage to a minimum and keep her sibling safer while being able to focus solely on her immediate needs.

A psychologist advised us to teach our son to verbalize the problem, rather than just exploding, We would cue him with certain phrases like, " Ouch! That hurt! Really hurt my hand (or whatever) and it was just an accident, Not my fault, just an accident..." After a lot of coaching he actually began to express what the problem was and we could talk about it. i don't know if your child would take to this. Just an idea. Good luck, it gets better.

Mama medication for her age bracket is not the solution for her I would recommend from my opinion, exercise with her that will help not only her meltdowns but also stimulation.... Hope this advice helps you God Bless....

And make sure she doesn’t let anyone even her teachers know was writing because they’ll try to turn the shit around trust you baby girl she your number is one ☝️ God Bless you Ma!!!!

Tell her to keep her journal 📓 and start writing ✍️ about her days at school even at lunch 🥙 time does she sit buy her self do they make fun of her weight that’s could be a very good indication as to why she throws her food away....
