Gurgle.com, owned by Mothercare, attracts a core audience of young British parents, from those trying for their first child to those with children under three years old.
Pettrina Keogh, managing director at Gurgle.com, said: "The development of blogging and UGC capabilities [on Gurgle.com] is but a stepping stone for further investment in social networking technology, to benefit both users and advertisers in the near future."
The site hopes that the addition of user-generated content and social networking features will improve interaction and communication between users.
Rob Proctor, head of EMEA at Reality Digital, said: "Today's internet users converse in both text and video-based media and expect a certain set and level of communication tools in any site.
"Given Gurgle's audience, blogging and other forms of social networking are a very natural forum for these young parents to share and collaborate in.
"These new capabilities are creating an environment for parents-to-be, in which they can share the story and build up to the greatest day of their lives with friends and loved ones."
