The new issue of Us Weekly has exclusive photos of Bullock and her 4-month-old adopted baby boy, Louis Bardo.
Baby store owner Jennifer Mazuelos tells Us that Bullock appeared to be "such a natural" while shopping for clothes with her fussy son in Austin, Tex. on May 14: "She was like, 'Oh, he needs to be held. She...was so easygoing and chill."
