Somebody alerted the party planning committee – because Mindy Kaling‘s son Spencer just turned 1 year old!

After celebrating the big milestone on September 3, the actress and producer took to Instagram on September 6 to share a photo of her little one for the first time. The cute snapshot showed Spencer sitting in front of a row of balloons. Kaling not only posted the precious picture, but also shed light on Spencer’s bond with his 3-year-old sister Katherine.

“Friday was my son Spencer’s first birthday,” she wrote in the caption. “My daughter Kit is pretty careful with new people. Not that guy.

Looking back on his birth, The Mindy Project star considered welcoming Spencer amid the coronavirus pandemic.

“I had Spencer during Covid and it was a strange isolated time, but as soon as I saw him I knew he was going to do everything better,” she continued. “And he did!”

At the end of her post, Kaling revealed her nickname for her youngest child and wrote, “Happy Birthday Spike!”
