DS is 15 months and his childminder mentioned the other day that she has been doing some makaton with him teaching him to sign thank you and explained a bit about it. I had never heard much about it or knew what it was really but I thought it sounded great, as did DP and we would really like to learn more about it and try it at home too. Just wondering if I should of started much earlier than 15 months? Have I left it a bit late? If this is something you done with your DC what did you think and what kind of signs did you start with?
