Hv has always said ds was very advanced but has speech probs so I sort of dismissed it as her being nice. However had a conversation today with a friend about her DD who is nearly 6 and DS who is 3 next week. He is eager to learn and some of things I said he can do she said are above average for her dds age group[she also has a ds about 6wks younger than my ds] He is my eldest so have no idea what is the norm.
