Last week, Dh was reading a science article on his phone when DS2 ran up to him. Dh tried to shut the phone off quickly and DS2 yelled, "Hey! I wanted to read that science thing!" There were not any contextual clues for him to gather that it was a science article. Then yesterday, DD4 is laboring through her BOB book and DS2 runs up behind her, reads the sentence she is struggling with and then hops away giggling. DD was so focused that she didn't even notice him. We just started the BOB books this week (I just learned of them last week)and I am hoping that DD will be fluently reading before she figures out her little brother is reading.
