It was a day of fresh Boston air for Jennifer Garner's little girls.
In the morning, Seraphina went out with her nanny for a bit before returning to join momma Jen and big sis Violet on an afternoon stroll around the park.
37-year-old Garner really got her work out today, pushing the stroller with one arm while toting Violet's tricycle in the other. After their venture around town, a very exhausted Jen packed up her girls and headed home.

She is so cute.
