There's sometimes a negative stigma around being the youngest sibling. You get it from both ends, too. You have the older siblings saying, "You have it so easy." Then you get the youngest siblings saying, "Ugh, I have so much to live up to."
There are complaints no matter what standing you are in your family, but as the youngest child, my unpopular opinion is that we actually do have it the easiest.
First of all, our older siblings paved the way for us. By the time it's our turn to start growing up, our parents have already seen it all. They know what to expect and they know how to handle us most effectively. We don't necessarily get in trouble for as many things as our older siblings did because our parents have already gone through the experience of raising other children and they understand it more now. Thus, making them slightly less strict than they may have been prior.
Also, although we may have a lot to live up to, having those successful and accomplished older siblings serve as people to look up to. They set an example for us and while that may be hard to live up to sometimes, they are still people we strive to be. They become a sort of motivational icon for us.
Additionally, you know you'll always be taken care of. You've got an army of older figures that are constantly looking out for you and that want the best for you. You always feel protected and loved because you have people worrying about you and your well-being all the time, especially when your siblings go off to college and you have all of your parents' attention on you...this can be a good and a bad thing.
Last but definitely not least, the hand-me-downs. This is for sure the best part of being a younger sibling. At least for me, it's a known fact that my sister dresses way better than I do. I eventually get all of her stylish clothes without actually having to spend the money on them. I get double the closet because of the amount that I receive from her and my cousins, as well as the clothes that I inevitably buy on my own.
As I said earlier, there are challenges of being the oldest, middle, and youngest sibling. I will admit to that, but being the youngest, in all honesty, is the easiest for the most part. I'm so grateful for my older siblings and all of the love and support they give their baby sister.
