My 3 year old is being a proper twat atm, pushing every boundary, refusing help for anything, making everything a fight. Best of many examples yesterday was when she made a massive mess all over the floor whilst I was cooking, my wife swept it all up and just as my wife finished she threw a ball directly on the dust pan to throw all the shit back all over the floor, then laughed hysterically. (tbf that was funny though)
You have just moved house right? Could be related
