Dd can read her school books pretty accurately: perhaps needing help or making a mistake on one word per book, or doing the whole lot without making a mistake.
For the past few books, she has refused to read the books properly and inserted silly words in the sentence. She's reading everything on the page but saying fart, poo, bum, toilet etc as well. (Think "the magic poo key began to fart glow") My approach so far has been to say "no extra words, please, just what's on the page", but this hasn't stopped her. I'm sure I can up the ante and give her more of a telling off but I don't like making mountains out of molehills.
Should I ask for her to be moved to some more challenging books or will her teacher think I'm batshit crazy? Should I simply wait for this to pass? I think her comprehension must be pretty good as she tends to insert the inappropriate words in appropriate places.
