signing is fantastic! I am definitely a supporter of teaching baby signing.....it is rather cute too as both my girls have put their own spin on the signs I agree that it actually enhances the vocab when you teach by signing and saying the word together. Its also been very useful when encouraging DD#1 to remember her manners.....mummy or daddy subtly signs "thankyou" and DD#1 pipes up, 'thank you!' hehe And for us, we have always taught "please and thank you" not 'ta' and DD naturally went from signing these words to saying them correctly......rather amusing when family asked for something or gave her something and said to her, "ta" and she'd look at them wondering what they meant! Teehee! - so again, I agree it boosts their vocab
