,Dear readers 

How was your summer vacation ? I am truly sorry that it took me a lot of time to update . I am very busy this summer because my examinations last until the end of Tir after that I went to mashhad in mordad & now I go to some  classes every day. this part is about language delay

 Q: What causes 'language delay'?    ۱

Language delay has a variety of causes which can include partial hearing, deafness, autism, visual impairment, severe sub-normality, cerebral palsy, physical differences (e.g. cleft palate), psychological disturbance, emotional difficulties, a high degree of social or emotional deprivation. In approximately two-thirds of all cases, the precise reason for language delay is not known. The evidence does not however support the belief that even some professionals hold that having a bilingual background can produce language delay
If your child is delayed in starting to speak or express themselves, seek professional help from a speech and language therapist

?How can we test if our children really has this problem

I think the best way to describe language delay is that , If your child have problems with his/her speech & speaking,  like : expressing him/herself e.g. finding words he/she wants to say. may have learning difficulties & be weak in Maths have problems communicating with others . Every time ask question he/she will not answer lacks confidence and etcIt does sound as if your child may have some difficulties with understanding speech or being able to express adequately. A speech and language therapist would look at all aspects of speech and communication and could advise you on ways of improving child skills
