How to use a ring stacker to build sounds and words. I've talked before about how echoic control (child repeating what you say) is important for building new sounds so let's make it fun. Grab a cause and effect toy with parts like a ring stacker. Say sounds like mmmm, aaaa, eeee or any sound or word you have heard the child say or babble as you give them a piece. It they repeat you , give the ring immediately. If not, repeat 3 times and give it to them. Need more ideas to support building words
