Claudia Barretto was among the first to greet her youngest sibling Erich on the latter's birthday last April 9, Tuesday.
The 19-year-old singer shared her touching birthday message for their family's bunso on Instagram in celebration of Erich's 7th birthday.
Claudia wrote, "My angel, you have no idea how much you’ve changed my life. You’re the best thing that ever happened to our family. Happy 7th birthday [heart emojis]."
It was in February 2018 when Claudia and her siblings formally introduced their youngest sister on their social media accounts.
Now, Erich can be seen regularly on her siblings' Instagram posts.
In an interview with PEP.ph (Philippine Entertainment Portal) last April 3, Wednesday, Claudia expressed how much she loves Erich.
"I love her. I'm obsessed with her," Claudia told PEP.ph at the opening of Loewe's store at Shangri-La Plaza in Mandaluyong City.
"She's the light of my life. Honestly, I don't know where I would be without her.
"I'm so happy that she's alive."
Claudia also thinks that she's Erich's favorite sibling.
"We have a very good relationship. I'd like to think I'm her favorite.
"I think we're alike on so many levels, like, we both have strong personalities.
"But, at the same time, we're also sensitive people. Like, a lot of things make us weak.
"And I love that about her. I don't know, we just really get along.
"She is just really mature for her age, so we also have really mature conversations with each other."
When asked if she thinks Erich is going to join showbiz one day, Claudia says her sister is ready to showcase her talents someday.
She said, "Totally, I think she'll be an entertainer one day. I don't know what field yet.
"But she's definitey one-of-a-kind. She likes to sing, she likes to dance.
"She knows how to play a little bit of piano. She's set for the entertainment industry."
Claudia added, "I think she can be many things at her stage now."
