Hi all, seeing as I was invited to join this group I think you might like to know I do research into deaf children's acquisition of British Sign Language and not 'babysigning'. The development of phonology, grammar and discourse in BSL is interesting but it doesn't lead to any long lasting language or cognitive advantages over spoken language development. This is 'babysigning' 24/7 throughout childhood. Do you have to be a hearing infant to get those advantages?
Another issue babysigning researchers should be aware of is the intense discomfort felt by the Deaf community about these products. Why would that be?
1 in 1000 babies are born deaf but only 10% or less acquire sign language as a native language. The paradox I see in the UK is that the vast majority of deaf children are not allowed to go anywhere near signing because it will 'slow down their language development'. Yet their hearing peers are encouraged to use gestures and borrowed BSL signs because it speeds development. Hard one to reconcile
