The Parent Bloggers Network, which launched today, will allow brands to target parent bloggers on their sites directly, giving them the opportunity to gives bloggers paid-product reviews or ask them for their product feedback.
Lego Games and Hasbro are the first brands to make use of the network to reach parent bloggers.
Siobhan Freegard, co-founder of Netmums, said: "Parenting bloggers have long complained that brands do not understand how to engage with them, often giving little thought to the age of their children or their particular living situation when offering them products to review or technology to engage with.
"We are launching the Parent Bloggers Network in response to these issues, to allow brands and bloggers to understand each other better and to interact in a new and mutually beneficial way."
Netmums launched in 2000 and claims to have over one million members in the UK.
Rival site Mumsnet is also expanding the opportunities for brands to interact with the parenting community, with its new Gransnet site.
