Zoe Saldana has "accepted the challenge" of raising three boys.
The 'Guardians of the Galaxy' star - who has three sons, two-year-old twins Cy and Bowie and one-month-old Zen, with her husband Marco Perego - loves being the "only girl" in her house and feels she has learned so much about men by raising her three sons.
She said: "We're done. I'm the only girl and it's OK. I'm enjoying being in a house full of men; I grew up in a house full of women, so I feel that either the universe is being ironic with me or it's being absolutely purposeful, and I'm accepting the challenge.
"I love raising boys. There's so much that I'm learning about men by seeing them in their early stages in life. Our kids are wonderful. They're happy!"
And the 38-year-old actress has gushed about her eldest children, whose curiosity is "at its highest peak right now".
She added: "Their curiosity is at its highest peak right now. We're just allowing them to guide us and let us know how they want us to parent them.
"We are a little meticulous when it comes to scheduling, so we're doing that, and we feel that our little one, Zen, is acclimating quite beautifully. I think that he misses his brothers when he's napping, because he's always looking like, 'Where are those loud things? Where are they?' It's great!"
And Cy and Bowie are equally great with their little brother and are "so excited" about the addition to the family.
She told E! News: "They're perfect. They're just marvelous, I'm telling you! I've heard horror stories of parents who have had to deal with dynamics that are a little challenging in the first stages of having a new baby, but they are so excited about him. But then they forget that he's there, because they're babies.
"They will walk all around him and you're like, 'Whoa, whoa, whoa! Wait, wait, wait! The baby's here; he's doing tummy time.' And they get all their toys and they want to show him their toys and they don't understand why he won't grab at them. But it's OK - it's all just a learning curve for us all."
