Thanks, Polar Bear. We're definitely going to continue to keep an eye on it. And to be honest, I'm also wondering about dysgraphia - he really struggles with letter formation, letter size and spacing of words. He also uses upper case and lower case letters in the same word and writes exceedingly slowly. His grade 1 teacher often comments on his writing skills.
We're getting a psychoeducational assessment done in May, so hopefully we'll have more answers then.
As for reading aloud, we'll continue to do it for as long as they'll let us!
