DS is in year R and enjoying it mostly (not as much as pre-school, but does like it) - he has been learning letters and comes home with homework sheets once a week. Socially he seems to be getting on fine, has made a few close friends and gets on with the others in the main (apart from the little oik who pushes him over in the playground )
Took him to the opticians recently and discovered he is long sighted - apparently this is normal, most children are long sighted until c.6 years old. He doesn't need glasses/treatment as it will right itself over a couple of years.
I have always felt 4 is a bit small to worry about learning to read/write - better just to enjoy books imo - and I know boys in particular are often not ready at this age.
But I was really surprised that we expect children to learn to read and write when it is normal for them not to be able to see/focus at short distances!
