Hilaria Baldwin and Alec Baldwin’s 4-month-old hits the carpet

Alec Baldwin and Hilaria Baldwin’s 5-year-old daughter, Carmen, is just the right age for kindergarten,

but that’s not who they brought to the Hamptons Film Festival screening of

“The Kindergarten Teacher” in New York this week. Riding shotgun against his mom’s

chest as she and Alec hit the red carpet was the couple’s newest addition,

4-month-old Romeo. Alec, who’s on the board of the festival, has been getting plenty of

experience in the fatherhood department since he and Hilaria fell in love.

In addition to Romeo, the two are parents to Carmen, 5, Rafael, 3, and Leonardo, 2. Alec also shared a daughter, Ireland Baldwin, with his ex, Kim Basinger. “Being a father can be very challenging because kids are obsessed with their mothers,” he told People in January. “I’m in a room with my kids and I’m doing really well until my wife walks in! They just dump me. That’s just how it is — there’s nothing I can do about it.” That reality led him to one tip for other fathers: “My advice for new dads,” he offered, “… If your wife is a great mommy, appreciate that and enjoy that. That’s a great thing to have.”
