My daughter gets confused when she writes D,C, P AND Q. How do I know if she is dyslexic?

Many preschoolers get confused when they start learning to write letters and letter reversals are very common. Dyslexia is only diagnosed when a child is about 6 years or around Primary one of age. However, early signs of possible dyslexia can be observed if there is persistent difficulties with recognising letters and learning letter sounds. Our local kindergarten teachers are good at flagging up their concerns usually in the second half of K1 or in K2.
