New York City-based Child’s Play Communications, which specializes in connecting companies with digital-savvy moms through word-of-mouth communications, has promoted Marie Baker to director of social media.

Baker will now be responsible for expanding and managing the agency’s social media immersion across Facebook, Twitter, blogs and other channels. She will continue to serve as director of Team Mom, the agency’s proprietary network of mom review-bloggers, as well as its offshoot, Music Moms, a music-industry-specific program targeted to mom bloggers.

Baker has managed traditional and social media campaigns for companies focusing on the mom market, including MEGA Brands and Universal Music. Prior to joining the agency in 2009, she represented children’s products as well as up-and-coming musical recording artists.
