We are going through a battle period too. I'd say we might be easing, but totally experiencing everything you described. This morning she woke up like a totally different person. Helped us with chores, ate her breakfast and got dressed without hitting me once!! So I'm hoping it was a short lived phase! My advice is just be consistent with boundaries and try your best to get through the chaos. It's hard going.
Yes, my LG has gone from such a sweet, helpful child to a little menace who wants to fight over every little thing đ I am hoping it is short-lived, and I am just trying not to react too much and be consistent and open with her as she tries to figure things out.
My boy is same everything is a battle
