Well we shall have to disagree milamae.
I also have worked for several years with primary and secondary children, as well as young adults, all from many walks of lives. I feel I also can make valid judgements.
Dd actually doesn't have loads and loads and only occasionally gets stuff throughout the year.She doeasn't have everything in the slightest, although IMo she has plenty, a lot, although not a great deal more than her other friends and family. Indeed some have a lot more. But she is privledged and lucky. At present she remains unspoilt. I see no reason why this should change so long as my and DH's parenting and views of things remain the same.
believe me I know very much the difference between this lifestyle and other lifestyles. My own background is very different.
I will ensure my DD is well brought up thank you very much. She is, in not just my own opinion, so far. there is nor eason for this to change.
And of course she will be well equipped for grown up, real life. As a responsible parent, who has very down to earth views, experiences and outlooks, I will ensure this, don't worry.
And, as I keep saying, my DD's nature at present does not lead to a spoilt child. It isn;t her at all. Maybe other children respond to things differently. What can I say, all children are different.
