Z is 6. He has 3 little brothers. He is a very good big brother and very helpful to his Mom and Dad. He knows a lot about babies.
His cousin, I is also 6, but he is the baby in his family. He was interested in Z's latest little brother and was discussing babies with his very experienced cousin. He learned a lot: They spit up. They poop and pee. They sneeze and snot goes everywhere. They get boogers in their eyes. And don't forget, they cry a lot.
