Hilary Duff baby weight jeans child baby

Hilary Duff's son Luca isn't quite old enough to be in school, but the former Disney starlet is giving her baby boy a head start, as we snapped her taking him to Babies First Class in Sherman Oaks on Wednesday.

The interactive mommy and me program was designed by occupational therapist Jackie Rosenberg, and "babies are stimulated with age-appropriate toys, as well as music and movement" in a group class setting of up to 15 families, according to the website.

When she's not focusing on her darling little boy, Hilary has been hitting the gym hard in an attempt to shed the remaining baby weight. "Obviously, I'm not where I want to be eventually, but I'm working hard and I'm doing everything I can to lose the weight the right way," Duff told Us Weekly earlier this year. "The second I start to get down like 'What happened to my body?' I look at my beautiful baby and I've never been more appreciative for this body that I have."
