@HEllo114 Strict consequences for poor behaviour.
Stick to them, don't give in.
Your Daughter clearly CAN behave, just chooses not to with you.
She will instinctively know you afraid of her ''kicking off''
Next time she kicks off, be firm, don't give in, and it will probably be a shock to her to see mum standing firm for once.
It doesn't matter if she makes a scene in Tesco or Waitrose, or in a Café- don't be phased by it.
No one will care, they will just be glad it's not their child creating a scene.
Almost all children can do this at some stage.
Your relatives say she is ''spoiled''...They probably can see the behaviours playing out in front of them - {it's much easier to see from a distance}-
She acts up in front of people as she thinks you won't feel comfortable disciplining her.
Your son- she could well be jealous of him, too. {The ''good'' boy who everyone likes. }
