The Curry house just got bigger.

Hearts filled with love, Steph and Ayesha Curry took to Instagram on Memorial Day to announce the exciting news of their son's arrival earlier this month. The infant is the fourth addition to the doting couple’s family.  

"Our sweet baby boy decided to make an early arrival!!" the caption read of the child who was born on May 11. "He’s doing great and we are finally settling in at home as a family of 6! So grateful!"

The post included a precious black and white photo of what appears to be a parent holding the baby's tiny hand. The post also revealed their baby boy's moniker: Caius Chai.

After making the announcement, the comment section of the post was lit up with support for the family.

"Congratulations 🎉🎊🎊🎊," said La La Anthony, while Yvonne Orji added, "Congrats you two!!!"

Ciara wrote "Congratulations," followed by three red heart emojis while new dad DDG gave a fun prediction for the future: "the 2042 NBA draft finna be crazy 😭🔥 congrats 🍾."

Along with Chai, Steph and Ayesha are also parents to daughters Riley, 11, and Ryan, 8, and son Canon, 5.

In March, Ayesha dropped a candid editorial in her online magazine, Sweet July, where she also revealed she was expecting.

"In all the noise, what I’ve learned about motherhood is that you truly need to trust yourself. You can read a million books and take 1,000 classes, but the most important thing is your maternal instinct," she elaborated. "You’re always going to know what’s best for you and your child. And no one’s situation is the same. The same way we’re unique individuals, we have unique parenting styles."
