Miriam Quiambao gives birth to baby boy

In a lengthy post via Instagram, the former beauty queen thanked Joshua for taking good care of his baby brother Elijah.

She wrote, “It seems gone were the days when he's been feeling threatened with the baby's impending arrival. Now he's so tender-hearted and just wants to be carrying Elijah every chance he gets. It's so cute to see them together.

“The little one recognizes Joshua's voice. Perhaps it's because Josh has been talking to Elijah even while I was still pregnant. The baby calms down whenever he hears his big brother's voice.”

“Elijah even gave him gifts when Kuya came to visit us at the hospital. One of them is this shirt that says “Best Kuya Ever.” I'm sure Kuya will live up to his new role. 🏼🏼️”

Miriam gave birth to her first child via emergency cesarean procedure last February 16.
