Need some advice ladies, so I know it's probably her age but Faye is becoming really bad with certain people, her dads side of the family she's being really off with and tries to hit them and when I tell her off, she hits me in the face but then carries on laughing and playing around. Doesn't matter how much I tell her no or how I tell her she doesn't listen. She's smashed a sentimental ornament this morning and continued to smash the door into the cabinet. She just has random outbursts of this behaviour then starts to play and dance like she was a few mins before. She knows she's doing wrong because she looks at me before she does it and does like a 'look what I'm doing face'. She won't play with any children when I take her places since a girl slapped her. I tried to show her it's okay not every child is nasty like that and now she thinks that's what you do, it takes ages to get her to play when before she would no bother. Any ideas on ways I can get her to calm down and how to get her to be okay at soft play and stuff?
