No longer a baby, but still our baby

I know a cool guy, his name's brother Z
And he is as awesome a kid as can be.
He's sporty and smart
Rocks the culinary art
But most importantly, he's got  huge heart.
Whenever we need him, and however he can
Z steps up and proves he's the man.
Whether he's protecting dear Momo
Or carrying big stuff
Our little guy is both so sweet and so tough.
And though it breaks my heart every time that I say
Our baby brother is 15 today!

Happy Birthday Z! You make us so proud everyday. You are surly the dessert in our 11-course meal of a family.
