Thoughts on these gifts for my family?

I was thinking of getting my older siblings iPhone 5s, they are aged 23 to 16 and my younger siblings aged 7 to 4 Nintando Ds3 XL's well my middle sibling aged 9 iPod touch. But I don't know what to get my mum, step dad, youngerest sister aged 2 and neice aged 3, Thoughts help?
And what do you think of the gifts I haved picked for my other siblings? Are they to young for them or not?
I thought to get my step dad and mum new Laptops or a camera?

Added (1). my older siblings are not older then me, I should have stated that. I'm the oldest by far, my mum and step dad are poor and they have been nagging for this stuff.
I said older siblings as they are the oldest of the ones living at home.

The DS3XL's are expensive the cheapest I have seen is $150.00 each

How about slippers for mum, stepdad, and the 2 and 3 year old.
They have the cutest slippers for little ones and I think mum and step/dad would appreciate it too.
Not everything has to be plugged in or entertain, its Christmas time to love your family not
over indulge them.

Your OLDER siblings are 16… And you're handing out I-phones. I-pads and DSXL's like candy?

Really?

Baby sitting money is that good these days, huh?

Hey, why not just get your mom and dad some gold coins while you're at it?

The 2 year old could probably use some designer duds.
