My 5 year old has literally turned into a monster during this lockdown. She is acting how she use to when she was 2-3. Shouting all the time, being mean and horrible to me dh and dd2 who is younger. Demanding things, saying we’re stupid. She says things for a reaction, she doesn’t srop when I say the consequences or how it makes people feel.. she laughs instead... she has changed and it’s really upsetting me. I don’t know what to do. It’s full on as I also have a baby but she still gets more attention than dd2
