My DS had major speech problems and had speech therapy for over 2 years. His therapist said he was mildly dyspraxic which fitted. He is now absolutely fine and apart from extremely messy handwriting and appalling spelling doing really well - even passed local 11+ exam. The reason I mention this is because I always had a reason why DS had appalling writing etc and I knew he just needed to catch up with the extra help.
My DD is 8.5 and in yr 4. She has exceptional vocabulary but cannot get her words down on paper. She can make up stories and talk about things but in class she can struggle to write a paragraph in the entire lesson. We found her to be shortsighted last summer and I thought that would cure things but it hasn't. So much so that she is now getting an extra literacy lesson with 3 others every day. Without being nasty, 2 of the other children are not very bright. The other girl is being tested for dyslexia. I just think there is an underlying problem with my DD too.
I'm at my wits end. When she reads to me it is slow and when she tries to spell out a word, she either adds letters that aren't there or misses them out. Its painful and I try to help but I know she can do so much more.
She has very low self confidence in new things and only learnt to ride her bike last summer.
