Melissa Joan Hart: I Want Another Baby But 'I'm Afraid of Girls'

The "Melissa & Joey" star is the mother of three young boys.

"I would like to have more. I'm not going to to say we're done having children," the "Melissa & Joey" star told ABC News, adding that while "it would be wonderful" to have a daughter, she wouldn't mind a fourth son.

"I'm scared of girls," she said. "If we had a girl it would almost be like an only child in a sense because she'd be so left out! We'd have to redo our whole house... new toys and new bikes. There are so many hand-me-downs in the family! It's awesome."

However, all of her boys are very different, Hart said.

"Mason is definitely the pioneer, the leader. Brady's very creative and also the adventurer. On Friday, he disappeared for an hour or so! He likes to get in small spaces and he freaks us out," she said. "Tucker's a lot like Mason. He's walking at nine-and-a-half months. He's the same as his brother, very strong."

And though she's not mourning the lack of estrogen in her house, her son Mason is.

"He keeps saying, 'We need to have another! We need to soften things up around here. We need a girl,'" she said. "But they've been watching 'My Little Pony' every morning, which is nice! It's different -- softer and prettier."
