Let me preface this by saying I know kids are all different and learn in different ways, at their own pace. I'm sure it's probably totally in the realms of normal but I'd like a little reassurance.
DS2 is 4, currently in nursery, starting primary one next year. He's a bright, happy wee boy who is doing really well socially now at nursery. He can count up to 20 (and beyond but not perfectly), count items, recognise numbers but he's got a complete block on letters. He knows maybe 10 of them, can't recognise them, never wants to try to write them. He has only recently started to attempt to write his name. I've tried encouraging it in lots of different, fun, engaging ways but he just doesn't like to learn. He's much more interested in cars and dinosaurs. He won't even draw.
His brother (6) was the absolute opposite. He adores learning and learnt lots of his phonics and was able to read before he started school. He's like a wee sponge. He was reading at the level of an 8 year old last year, is doing a fairly good job with writing/spelling and is exceeding expectations at maths too. He enjoys arts and crafts, science etc.
AIBU to be a bit concerned? Any helpful strategies to get him to have an interest in learning?
