Mumsnet is featuring the Childhood Eye Cancer Trust as its guest campaign this week.

To mark World Sight Day, the parenting website is helping to raise awareness of retinoblastoma by showing our Uninvisible Friend campaign on its website.

Each month Mumsnet chooses a selection of campaigns by charities or not for profit organisations that it thinks will be of interest to Mumsnetters.

Thanks for your support Mumsnet!

See the guest campaign.
