This didn't really come up in conversation with mine. 😂
I honestly don't know. But DS was very slow to get reading in reception. He would repeatedly respond with dog to us desperately spelling out c-a-t. He has got a good sense of humour though.
He went on to be exceeding in reading. He read every night and would happily tackle any book you gave him. Sadly he seemed to quit reading for pleasure at 12. I think you can just try to enjoy taking the horse to water and don't invest too much emotion into the drinking part.
