DD1 started reception this year.
On day 2 she was given a reading book and diary (initially without words but has since progressed to basic words) with instructions to document when she read at home and leave it in the book changing box at school once she'd read in twice. We also got a letter explaining that they woukd aim to hear children read once a week but it may be less at busy times of year. 
To date no-one has heard DD read. (4 weeks)
Now I know reading isn't the be all and end all but its my only outside measure of attention DD recieves in school - and in a month there's none!
What is normal? Are my expectations too high? I'm worried that I'm doing reading 'wrong' as she's struggling to blend the letter sounds together - but despite documenting this in her reading diary - nothing. Is it ok that DD seems to get most of her clues from combining the first sound of the word with the picture in the book?
