I have a 11 yr old daughter who is a real nightmare it first started when she would come down in the morning and sneak food out the cupboard or shed open a box of chocolates and put the seal back on the packet to make out we were stupid then the lies and its constant lies and then now we have money missing out of our wardrobe and wallets, we found over £10 of sweets in her draw at home she comes in from outside and runs straight upstairs. We have 5 children so we reward them in our weekly shop as pocket money is quite a push. She never does nothing her bedroom is a mess she never tidys the mess she makes she is just so lazy!! We have thought about it and maybe she could be doing it for friends or attention but we give all 5 loads of attention.. Iam in a state where i dont trust her i hide everything and i keep track of what is where and how many. When confronted she lies and gets all upset and then 2 days after being ok shes back to square 1 and then we have the other problem i ran a bath and she used the toilet and when finished i went in and got in the bath shed put toothpaste in my bath!! how evil!! She also teases her sisters and hits them and when asked she lies even though there are marks left. What do i do i cant deal with the screaming and shouting kicking doors slamming doors its not fair on the other 4 whats it teaching them
