Hilaria Baldwin / instagram Hilaria Baldwin Says Having Two Babies Is 'So Fun and Cute,' but Admits 'There Are Also Challenges' Earlier this month, Hilaria got candid on her Instagram Story about juggling son Edu and newborn daughter Lucía, writing: "Having two small babies is so fun and cute. there are also challenges. like Lucia just had an explosion and I have Eduardo rolling around...so I'm just gonna lay here, covered in poop, entertaining Edu...until I get a genius idea how to get out of this 💩 situation." In another Instagram post, Hilaria said the family feels "overwhelmed by how fortunate we are" to have their "rainbow baby" Edu, adding of their newborn girl: "We are living each day, bonding, and grateful for all of the very special angels who helped bring Lucía into the world." Hilaria Baldwin's Daughter Carmen, 7, Snuggles with Newborn Lucia After Years of Asking for Sister News of her sixth child's arrival came a month after the Mom Brain podcast co-host apologized in February for not being "more clear" about her cultural background when she was accused of misrepresenting her heritage in late December. Social media users alleged she had falsely claimed to have Spanish roots and took on a Spanish accent despite being born and raised in the United States. "I've spent the last month listening, reflecting, and asking myself how I can learn and grow. My parents raised my brother and me with two cultures, American and Spanish, and I feel a true sense of belonging to both," said Hilaria, who previously confirmed that she was born in Boston and her birth name is Hillary. "The way I've spoken about myself and my deep connection to two cultures could have been better explained — I should have been more clear and I'm sorry."
