Middle Child Struggles

Being the middle sibling is tough. My older sister gets all the attention for being the perfect one and my younger brother is adorable, so everyone spoils him rotten. I feel stuck in the middle, like no one really notices me unless I cause a problem. It’s not that I’m jealous exactly; more just...sad. Do other people who are middle kids feel this way too? Is it normal to always be looking for ways to get noticed?
