Two days since Sarah Lahbati gave birth to Kai, her second son with Richard Gutierrez, the baby's photo is now all over the Internet.
Zion Gutierrez has also starting his new role as kuya.
Here's the four-year-old boy appearing playful with his little brother.
In Sarah’s latest Instagram video, Zion was up to the challenge of putting Kai to sleep.
His trick? Singing!
Zion sang the French song "La Vie en Rose."
His mom's caption read, “I’m on cloud nine [cloud emoji] Here’s Zion singing Kai to sleep. [heart emoji] @officialziongutz @richardgutz #stillworkingonthelyrics.”
Sarah gave birth on March 21.
