A Letter To My Son

To my sweet boy,
I’m just going to come out and say it: it sucks to be a younger sibling.  I can’t say I know how you feel, because as a firstborn, I have never been in your shoes. But I remember how I used to treat my little brother, and I wouldn't have traded places with him for anything.  
As your mom, my heart breaks for you every time that your sister hurts your feelings, or leaves you out, or makes you feel like a second class citizen.  I think there must be something to the idea of karma, because with every heartbreak, I’m reminded of how mean I was to your uncle, and I see now how wrong I was for that.
