My dd is 15. In the summer we set her up with her own bank account into which we pay performance related pocket money and she's just had a birthday so there are Is also birthday money in there - albeit a but depleted thanks to multiple orders to PLT
. She also spent about £100 on her boyfriend for his birthday 
It's her dad's birthday next week and she's refused to fund his gift as its "her birthday money so she should spend it on herself"....but there's also tge pocket money element in there.
I feel sad she's taking this stance. It hurts that she can spend so much on her boyfriend but has no inclination to want to spend anything on her dad. Another PLT order turned up today....shame she didn't think to spend that £15 on him. She does so little for us, it's all typical teenage me, me attitude.
I feel I shoukd refuse to fund it. If I do it's highly likely he won't get anything from her as she won't be bothered. I don't want him to feel like she hasn't been bothered....but if i fund it, I'm propping her up and taking any responsibility away from her. I'm not sure whether I'm being unreasonable....maybe this should be in AIBU!!
Do you expect your teens to buy their gifts?
