language delay

[maa1]

HISTORY-  i have a 3 yr old son.his growth charts and other developments have been normal,the only slight delay being in onset of teething(around 11 mth).However,he was not responding to his name or saying mama or papa by age of 2 and half.We consulted his paediatrician and he advised to wait for 6 mths and watch for autism /ADHD.

C/C-even though he uses some words like names and points to some 20-30 vegetables and fruits ,objects like umbrella,watch,clock,tv,mobiles etc.,maintains eye contact,no eating or sleeping disorder,usually cheerful and happy,displays emotions and responds to them,joyfully sings some nursery rhymes in both hindi and english, loves scribbling with crayons.hes very active physically,loves tasks with physical manouevering(climbing,swimming,swinging,ruuning etc
but he doesnot obey commands,doesnot respond to his name,doesnot say mummy or papa,doesnot interact much with children(though he does play with older and known children),repeatedly lines up his toys, vehicles and even, stools and chairs at times and insists on it not being removed or disturbed,communicates his needs by using our hands (to point at things )and gestures,is aggressive at times and resorts to tantrums mostly,doesnot take turns or even stand in que.Sometimes ,i feel hes using certain words and even phrases with understanding what they mean.
We started his play school around mid january. end of May,made some good progress also,started singing poems,telling colours,saying courtesies like hello ,babye and thank you.now suddenly,hes completely awash.....doesnt sing that many rhymes and that too frequently,speaks too gibbrish,his vocabulary has started shrinking(recognizes less no. of things),if we are persuasive,he would try to speak out any word he can remember. his school teachers  told me that he is way behind his peers and  advised to visit a psychiatrist for a DQ test(development quotient test).
      im really worried plz advise

He should be evaluated by a developmental pediatrician. There is no question that in the area of speech/language he is delayed and there are indicatins his social development is also delayed. It is possible that he displays a type of pervasive developmental disorder, but the only way to know this is have him evaluated in all the major areas of development (motor, cognitive, social, emotional). This has nothing to do with ADHD and, in any case, he is far too young to be adequateluy evaluated in that area.

A developmenatl psychologist could also be consulted, though the best resource would be a developmental pediatrician. I cannot go into the details of such an evaluation her - it is too exhaustive a process. The technique mostly revolves around observation, discussion with parents, review of history, a physical examination, usually no imaging or laboratory studies. If you do an internet serach for DEVELOPMENTAL EVALUATION you will learn more than you even need to know.
