milliec - the focus of your post is erroneous.instead of focussing on what the boy cannot do why dont you look at the positives.
progressing to reading comes from
listening pleasure in been read to
rate tone repetition of words
he cuddles up
he listens attentively
his mum obviously reads
it is unfair to cast aspersions on a toddler reading and his sibling- sheesh you are supposed to be a friend
Very unkind to suggest exaggerated school reports. if they tell you they are "getting really good school reports and doing well" you as a friend should accept this. not silently scoff and doubt about them and school ability.
