dd turned 15 last week
For her birthday i bought her over £100 worth of summer clothes, she also wanted her hair coloured so we treated her to that which was £75, then we had a family meal out to her fave restaurant.
The following dayshe decided she wanted to go into town to spend some birthday money, she wanted another bikini, a strapless bra and some dvds. I said i was happy for her to get the stuff but not the dvds.
She went nuts banging on the walls and shouting that she should be allowed to spend her own money on whatever she likes. She also wrote on facebook 'thats right mum, take your fave son out to buy him a present, but i cant even spend my own money' 
I wanted her to save some money as over the next few weeks she has a trip to barcelona with school, a trip to london with her nana (because i wouldnt take her again having already taken her once this year and taking her again in october), then our family holiday to spain, then a surfing weekend
Yesterday i asked if she would like to go to GBK for lunch as a thank you for her babysitting a few hours last night, however this morning she screamed at her little brother and was so rude i asked her to go to her room, she has spent the whole morning lying in bed then got up at 11.30 and said 'what time are we going to lunch' i told her i wasnt taking her because her attitude towards me and the boys was so terrible and she screamed at me 'god dont you realise i looked after your kids last night'!
I just dont know where to go from here, AIBU and expecting too much, or is she a nasty spoilt brat? She makes me feel like i treat her like shit, but i dont think i do.
