I have an 8 year old nephew, who has been quite spoiled by his parents. His parents are older parents, because he's the baby of the family he's been quite spoiled. I could list some of his behaviours but we'd be here forever and a day.
One thing that has been happening more frequently is him asking for things in my home, such as toys that belong to my children etc that my children don't want to give away, nor have I offered it to the child. It'll usually be: "Can I have [insert item here]"?" (never followed by please or thank you). When I tell him no due to the fact that it belongs to my DD or DS, he will sulk.
What made me ask for advice on this forum is something that occured this evening. My nephew had felt tired so DD had gotten a blanket for him to keep him warm. She had explained to him that this was a very special blanket since it was what their late Grandmother had given to her (he never got to meet his Grandmother). This later on in the evening was proceeded by: "Nanny said I could have this blanket". Now I know for a fact that there is no chance that DD would ever part with it, and quite rightly she said no, because it was given to her. He then repeatedly kept saying: "Nanny said I could have it" and tried snatching it off her, sulking when she said no. Eventually, DD had to go and hide it when he wasn't looking.
I later explained to him that he couldn't keep asking people for their belongings, since "You wouldn't like it if people kept asking if they could have your XBox or iPad". However, this is never followed up by my nephews parents. It can be very difficult to speak to his parents (well more so his Dad) since I would get told to "mind my own business".
What can I do? He's certainly not a deprived child.
