Anna Faris is already a pro at motherhood. The 36-year-old What's Your Number? actress took her 9-month-old baby boy, Jack, for a stroll in L.A. on Tuesday, June 4, and did everything in her power to keep him happy.

Faris, who welcomed her son with husband Chris Pratt last August, cradled Jack in her arms while walking around The Grove. Dressed in a t-shirt, skinny jeans and cap, the new mom had a smile on her face during the outing. Jack, wearing a cute blue onesie and socks that looked like sneakers, however, appeared to be a little fussy.

Faris tried to figure out how to make Jack happy by showering him with kisses, and even using the smell test to check for a dirty diaper.

The actress gushed to Us Weekly in May that she can't get enough of her son. "It makes me crazy when I'm not holding him," she said. "He's at a really adorable phase. He's not crawling, but he sort of wiggles. He coos and he giggles and he makes funny, funny noises."

But her husband is always there to give her a helping hand when she needs it. "Chris is an amazing dad. He really is," Faris said of the Parks and Recreation star, 33. "He feeds the baby almost every morning so I can sleep in . . . It's very sexy to watch him be a dad!"
