He was 6.8 lbs. at birth and he's healthy and happy and even his occasional hiccups, are to me, adorable," Cooper said, sharing that the newborn was welcomed via surrogate. Courtesy of Anderson Cooper "He mostly just sleeps and eats and certainly poops, but he already seems like a wise and thoughtful little chap." Anderson Cooper Announces the Birth of His Second Baby, Reveals Benjamin Maisani Is Adopting Son Wyatt Although Cooper announced the end of his and Maisani's romantic relationship in 2018, the pair has remained close. Maisani was also in the delivery room during Wyatt's birth in 2020. Speaking with PEOPLE in September last year, the CNN star opened up about co-parenting with his ex, saying, "It's awesome. It's probably an unusual setup, but I knew he would be a great dad, and he is. We're exes, but we're family to each other, and we love each other as family and as co-parents." "There's the usual bickering that any two people have when there's a kid involved, like what time should he go to swimming class, or should he wear the overalls, or whatever," Cooper admitted, adding, "we get along great." "I've always believed that if you've been with somebody and that ends, in terms of an intimate relationship, if you love somebody, there's no reason why that love shouldn't continue," he said.
