My Dd is the youngest in her class and will be 4 in July.
She can sound out words, and write letters, count up to 60 and down from 10, add and subtract. I'm more impressed by her mathsy tendencies tbh.
we have no telly either and the preschool Montessori teacher has told me that DD's very bright. She could identify and sound out letters at 2 and a half.
DD's always been very dexterous and could hold a pen as soon as she picked it up. She's very right-handed. We taught her sign language before she was verbal, and she communicated her needs very well then - DD had few tantrums during the terrible twos - i had most of them
I'm worried about her starting school in September as she will be the youngest again, and also about her being bored if I leave her in her pre-school. I don't want to push her academically, or hothouse her or anything like that, as she'll be in school for years and years, so there's plenty of time.
I read at three and a half, as did one sister - my other sister was 5, and was a lot more artistic and creative.
I think it's all swings and roundabouts. Some kids are more developed at one thing, and not at another, and then everything evens out.
Are you thinking of starting your DS off in pre-school this September? On the basis of the similarities between your DS and my DD, and what my DDs teach told me, your son is 'bright', but it's probably not that unusual on Mumsnet, because of the user demographic
