A group that campaigns for the rights of separated fathers and unmarried families has called on people to vote no in the forthcoming Children's Referendum.
The group said the amendment does not go far enough and the Government should come up with a better proposal.
Meanwhile Sinn Féin has launched its campaign for a yes vote.
It said it is a worthwhile proposal even though it falls short of the party's policy.
The referendum is due to be held on Saturday, 10 November and a number of groups, charities and political parties have already launched their campaigns.
