I didn't really start this thread as a place to debate the relative merits of starting solids at differant ages. If you disagree with WHO and the body of scientific research then so be it. It doesn't affect me and you can simply choose not to write to any baby food companies.
If like me you choose to follow WHO recomendations and would like to see ethical labelling then please write to the companies involved and add the contact details of any other companies you see who label their food incorrectly.
And maybe send an email to anyone you think might be interested.
