Cool video. Click on the link. It's from the association known as the BDA:
‘Signing Family' , produced by Deaf Association of Northern Ireland, is an information resource for parents of Deaf children, Deaf parents of hearing children and professionals. It is a multilingual information resource parented in British Sign Language (BSL) and Irish Sign Language (ISL) with English voice over and subtitles.
The DVD presents the most current research to demonstrate that a bilingual approach and introducing sign language to your child early on will give them the best opportunity in life.
This is so smart - create a resource based on modern research and maximise your audience to three groups instead of advertising it only to one.
