The 37-year-old author revealed this week she has become a mother for the sixth time to a daughter named Lucia – whose full name is Maria Lucia Victoria Baldwin – after she was born via surrogate, and has now sent her thanks to everyone involved in bringing the tot into the world.

Hilaria posted a picture on Instagram of Lucia and her six-month-old son Eduardo sharing a sweet cuddle, and said she felt so “fortunate” to have welcomed her two youngest children after suffering a miscarriage in 2019.

She wrote in a lengthy post: “Our hearts are filled with so much gratitude. The Baldwinitos craved so much to have a little sister.

“Many of you may remember the loss of their sister at 4 months in the end of 2019. There isn’t a day that goes by where we don’t ache for our daughter. When I found out our baby had died, I told our children that their sister was going to come, just not at that time. Nothing will ever replace her, but two wonderful souls have come into our lives, and we are humbled to know them.

“Our children were brave during our time of tremendous grief—braver than us...and they held out hope. To experience and accept life’s ups and downs is challenging, but a reality that all of us have no choice but to receive and process. I have learned that often our children are wiser than we are and their wisdom has guided us.

“Our rainbow baby, Edu, is such a blessing—we are overwhelmed by how fortunate we are to have him. We are living each day, bonding, and grateful for all of the very special angels who helped bring Lucía into the world.

“María Lucía Victoria and Eduardo Pau Lucas: our babies who bring light into our lives—almost like twins, we love you so much. (sic)”

Hilaria – who has Lucia and Eduardo, as well as Carmen, seven, Rafael, five, Leonardo, four, and Romeo, two, with her husband Alec Baldwin – recently said she is “so in love” with her latest arrival.

She posted earlier this week: "We are so in love with our daughter, Lucia. Just like your brothers and sisters, you are a dream come true."
