Little sisters have been annoying big sisters since the beginning of time. After all, you were their very first playmate, their first friend, their first teacher. They feel like you belong to them. Now that you are growing up and stretching your wings further outside the nest, she misses you. That’s why she’ll do whatever it takes to get your attention. Even going so far as to make you mad by tattling to Mom. Even if you’re yelling at her, you’re paying attention to her.
This is a challenging time for both of you. You’re trying many new things, learning more about people and the world, taking steps toward adulthood, and she’s still hovering on the brink of childhood, unable to catch up with you.
I promise, in a few years, you and your sisters will be best of friends. In the meantime, try to be patient and when she gets on your nerves most remind yourself it’s because she loves you and is afraid she’s losing you.
