New Baby Brother

I was sitting in school

when I heard the news.

“Your baby brother is born,

and wants to see you!”

Dad got me from school and to the hospital with no delay.

Hurrying on ourjourney,

he almost forgot the way!

My brother's hands were tiny,

and wrinkly soft, like a prune.

After he smiled at me,

Mom said, “He'llcome home soon!”

Everyone “oohing”and “aahing”,

they say “He is so sweet.

And one day  he'll walk around

on those little baby feet!”
