Don't I spoil my niece too much?

My niece is 21 years old I love her but I think I've been spoiling her too much. She can be a brat sometimes. She has an iPod Touch and a phone and a laptop and I bought her a tablet for Christmas now she's wanting an iPhone. She just wants one because all her friends have one. And when I go in her room she tells me to pick up her clothes for her and she throws her pajamas on the floor and I tell her she can wear them another night or two but she tells me its disgusting and she won't do it. And she makes me by her an iTunes card every week even though she has 10 or 15 dollars left on the one she already has. And she paints her nails different colors every week. She has about every nail color you can think of she wants to by purple nail polish every time we go to the store because purple is her favorite but she's got 5 or 10 shades of purple. And when she doesn't get something she doesn't want she tells me " I want it now! " she tells me that until I get it for her. And she we get her a case for her iPod about every 2 months because she always looses them or breaks them same thing with her phone. But her phone is an android lg flip phone so we have an awful time finding a case for her phone. And she always wants something purple or sparkly every time we go shopping and if she can't get it she gets mad at me and her boyfriend. What do you think? Am I spoiling her too much? Is it normal and how can we make her stop?

Well personally I believe that you're spoiling her too much. She will stop if you stop doing everything she asks. I'm not saying you should say no to everything but when you see for example that she has money you don't need to give her more. I'm a year older that her so I believe that in our age we must learn to stand on our own feet and become independent. I do understand that you love her too much and you can't tell her no easily, I'm like that with my sister, but eventually she will have to learn how to deal with some things on her own. And trust me when I say she won't be able to if she have learnt to rely on you.

I'm sorry I stopped reading your paragraph half way through its to obvious. SHE'S 21! She should b working n buying most of her stuf by her self! One day you won't be their for her n she's gana b like omg I have to buy my own stuff n pick up my own clothes this isn't right! That's life she's never gana learn to b a mature responsible adult. Sorry of it seams like I'm being harsh but I'm being honest. If you really loved her and cared about her future you would stop babying her because thats not gana help her future at all. You no what she's callable
of and I think picking up her own stuff and getting a job to buy her
own stuff is some of it. Good luck and you seam like such a nice person
and if you thi k that she won't love you when you stop treating her like a
princess, she's prob gana mad but it's for her own good… Now to make her stop you have to stop giving in! Stick to your answer as no! And don't change your mind, if you do she will learn that eventually she will get what she wants.
