Background: my dad is definitely dyslexic, my DB has learning difficulties (reading, writing, maths) and aspergers.
DD 3.5 can sometimes seem completely normal and quite bright. For example, knows her letters and numbers, shapes, remembers things from ages ago e.g. Previous location of swimming lessons (changed location at 2.5 but she still remembers old pool.)
But, every day she has accidents (wet) at school nursery, and her speech and comprehension can be rubbish. She uses 'he' and 'her' indiscriminately, whichever she fancies regardless of actual gender of people. If asked what she wants to do today, she tells you what she did yesterday. If asked what she did at school today, she has a strop and says her head hurts. Other kids her age can chat for ages on the topic. The other day, 2 just turned 3 year olds she knows from school, saw her in the street and were all excited to see her. DD looked as though she'd never seen them in her life before.
So, does she sound a bit like she has SN or not?! Can never make my mind up, but always worry with my family background.
