How Primo and Leon reacted to arrival of baby sister Alana

All is well in Casa Arellano after Iya and Drew brought Baby Alana Lauren home sweet home.

The couple decided to keep the baby's gender a surprise

The two toddlers apparently responded in contrasting ways, as shared by their mother Iya in Aubrey Carampel's report for "24 Oras."

"Si Primo parang mas aware siya tapos siya excited. Sobra siyang excited na makita 'yung kapatid niya even if ang gusto niya sana talaga e baby brother," she said.

On Iya's Instagram Stories, Primo was spotted already trying to play with his sister.

The younger Leon, meanwhile, was more cautious in approaching Baby Alana.

"Naawa ako kay Leon kasi parang 'yung tingin niya parang, 'Ano 'yan?' at saka 'Sino 'yan?' Medyo natakot siyang lumapit tapos medyo umiyak siya ng konti," Iya said.

"Sobrang alanganin si Leon pero ngayon unti unti na siyang lumalapit," she added.

And what about the parents? With Alana only two days old, their observation so far is that she is a "sleeper."

"Mas matakaw siya sa tulog, ang haba ng daliri niya sa paa. Mas malaki siya, ito 'yung pinakamalaki kong baby," Iya said. —MGP, GMA News
