The baby arrived on Monday Sept. 12 at 6:51 pm in New York City. "We are so pleased to introduce you to our new baby, Leonardo Ángel Charles Baldwin. It was such a special day bringing him into this world," was the caption Hilaria, 32, included with a snapshot showing her cradling the new arrival shortly after his birth.

Little Leonardo is a new baby brother for three-year-old Carmen Gabriela, and 14-month-old Rafael Thomas, as well as Alec's 20-year-old daughter Ireland.

"Ireland, Carmen, Rafael, Alec and I are excited to share with you that we are going to have another addition to our family," she wrote on Instagram. "A little boy coming this fall."

The yoga instructor has also been using social media to document her pregnancy, chronicling the growth of her baby bump with a series of mirror selfies and other photographs.

She explained her motivation for doing so in an Instagram post shortly after announcing her third pregnancy.

Sharing a side view of her small baby bump, Hilaria wrote: "And we begin the journey again! #BaldwinBabyBump3 I posted belly photos every two weeks when I was pregnant with Rafa. I didn't have the guts to do it the first time round with Carmen. The purpose? To show that we don't need to be ashamed or hide the pregnant figure. These are common emotions in our society that elevates a thin body above all else.

She added: "Being my third baby in three years, I am a true believer that our bodies are amazing, and we should celebrate them , rather than feel embarrassed and hide until the baby weight is entirely gone.

"For both women and men: we create life… so let's honor how we make these miracles. Every pregnancy is different, so we shall see what happens this time around, ready to take the journey with me? Deep breath, pressing "share"… #366daysoflivingclearly #HilariaLCM."
