Scooping up her daughter for a hug (she hung her upside down soon after!) Nicole Richie enjoys an afternoon at the park with a smiley Harlow Winter Kate on Wednesday in Los Angeles.

She’s a happy girl — Joel Madden twittered earlier today that Harlow was waving at everyone while out with him!

The 16-month-old will become a big sister later this year, with Nicole and Joel expected to welcome a sibling for her in late August.

Harlow wears PUMA Infant/Toddler Future Cat L Sneaker ($32). She’s also wearing Juicy Couture Baby’s Striped Dress and Navy Leggings.
