Good on you, Megsmum, I think it's great your little one enjoys reading so much! I loved reading as a child, and its an attitude I try and foster in my children. That said, I think it's easy to forget how hard it is to get a child to do something they don't want to do, especially when it is an activity (like reading) that our own children love.
Molly is getting home readers sent home, two a week, and you know what? I am struggling to get through them as well! Between finding time to read the two library books she religiously borrows each week, practicing her sight words booklet, and letting Olivia choose a book occasionally for her bedtime story, it actually becomes quite difficult to get through two home readers a week. So to a certain extent, I can sympathise for that Mum - I dread what we'll do when extracurricular activities start to gain pace.
