My dd (5.5) is in the same boat. I have decided to stop OPG for the time being and I am just having her read what she is comfortably capable of. That means that we are simply reading all of the "level one" super basic books such as Nora Gaydos, Bob Books and SL K readers.
It got to the point where anytime she was asked about how she liked school, she would say, "I like it except I don't like reading." Or as the other poster mentioned, my dd would hide as well when it was phonics/reading time.
I just feel like this much resistance is a red flag that we need to cool it for a bit so she can gain some confidence and basic fluency through reading simple stories. Its hard because I know she is capable but she just is not quite ready yet, and well, thats okay. My main objective is to cultivate a love of learning and reading and I know that I will have to achieve that in baby steps.
