Broadly I know what it is, but at what age is it diagnosed usually? I ask because DS is only 4.5yrs and the school have said that it's too early to diagnose yet, but in future he may need to be assessed. Basically he can't decide which hand to use and is v.v. confused by this. He doesn't hold his pencil properly and doesn't seem able to write any letters. He also struggles to represent shapes in the air. Whilst he can count how many people etc are in the room, when he looks at numbers on paper (unless you show him just a single number) then his counting goes all over the place. He sees 9 as 6. His teacher siad that mirroring is v. common in lh children. I'm lh and a bit ambidextrous and DH is rh. He is quite clumsy and unco-ordinated - ie things like jumping, hopping etc. He spoke quite late - only really started to interact properly at the age of 3 and really properly when he started pre-school. Anyone got any ideas?
