between once and 3 times a week. I do not force her. I ask her if she would like to read to me, slightly directional, if she is tired, had a long day or we are busy out to dinner, i don't. Sometimes she reads the whole thing, sometimes a couple of pages before she gets frustrated/distracted/bored. I do not push her particularly hard, or set small challenges (if on page 3 - ok, lets read to to page 5 then you can stop ok?).
We get a new book every time she reads the one she has. Sometimes this is due to being read at home, sometimes it is read in class to teacher/ta/parent helper, then it is changed.
She does however like to read her own books now, she will pick up a book such as Dear Zoo (back in circulation as 15mth old loves it) and she will practice reading it, sometimes on her own, or to her brother, her dolls, or to us.
She also likes to 'read' my books and pick out letters/words she recognises
