Children learn at different paces. Their school marks are a sign of their competency and the speed with which they can learn skills, also how they will fare in life in general. Thus, if your child isn't able to cope up with reading and writing for a while, it could be signs of dyslexia. Most children are diagnosed with dyslexia in third-fifth standard.
Here are three early signs of dyslexia in children:
Often has problems naming familiar objects, saying general words like thing and stuff instead of the names of objects.
Has trouble learning a new word, even after you’ve tried to teach it to him many times.
Has trouble learning nursery rhymes or song lyrics that rhyme, and has difficulty recognizing and producing rhymes.
