Why Learn Auslan for Babies?
I have two older children aged 23 and 20 and they have signed all their lives. The main takeaway from both children is that they are expressive, creative, perceptive who sign well and speak normally.
I also have a 5 year old who, when he was 3 could sign 450 signs and knew twice as many more that he could not sign due to the continuing development of his fine and gross motor skills.
He did not have the terrible twos as we could understand his needs and he was a happy, bright and very alert baby / toddler who started speaking much earlier than other children his age.
Learning Auslan as a baby / toddler does not make children smarter. However it makes them more alert, watchful - good eye contact, happier and they are bilingual which is always good for left and right hemisphere brain development.
