With sources confirming Jennifer Garner is four months pregnant with her second child with Ben Affleck, the couple are being praised as loving, attentive parents.

Joey Parsi, owner of the indoor L.A. playground Giggles N' Hugs, where the actress recently visited with daughter Violet, 2, says Garner, 36, is "the perfect mom, and, trust me, I've seen hundreds of mothers in here."

Affleck, 35, also is "totally insane about Violet," says one of his longtime friends. "I know how much he enjoys being a parent. He gushes over Violet. He says she's really smart, she's really verbal and she's got a funny personality. He's happy to be a father and she's happy to be a mother."

And so friends were hardly surprised to hear the news that a source confirms to PEOPLE. "She's pregnant," says the source.
