A large South End space awash with natural light, Little Lovage Club is a different kind of baby boutique. Owned by Jessica Runnals, it offers classes for tots during the week (check out Messy Munchkins for playtime without the cleanup); on the weekends, it transforms into a birthday-and-event venue that helps parents plan Instagram-worthy theme parties. And adult classes on breastfeeding and CPR mean parents-to-be can sleep like a baby knowing they’re set for their little one to arrive.
