Earlier today — 6th August 2025 — Isaac’s mum took to Instagram to share the heart-melting news: the arrival of Isaac Kearney’s baby sibling, Sonny Kearney.
She posted a short video around 3pm, captioning it:
“Sonny Kearney – 6th August 2025, The day our family was complete forever 💙”
But what really set social media ablaze wasn’t just the birth — it was Isaac’s reaction.
In the video, Isaac and his sister Florence are seen walking into the hospital room. The moment Isaac spotted the newborn, he joyfully shouted:
“hello Sonny!”
As if that wasn’t enough to melt hearts, Florence leaned in to kiss her baby brother, while Isaac confidently grabbed the feeder to help feed him — showing just how ready he is to be a big brother.
The wholesome scene has already sent fans into a frenzy, flooding the comments with love, congratulations, and heart emojis.
“Isaac is literally the sweetest big bro ever 😭”
“Can’t handle this cuteness 😍 Sonny is blessed already!”
“That shout — ‘It’s Sonny!’ — made my day 🥺”
