i think your son is a wise boy , don' t worry
My kid is 2 years old but he also does not say "pa" or "ma". But he can say "apple", "moon", "bye", "OK" and some alphabetics and "I hold it" & "I need it" (in Cantonese) etc. He can also follow some simple instructions from us at home. During the checking of the health clinic, he just refused to point out the photos that the nurse requested for, then the nurse worried about he maybe problematic at 理解能力. I felt the nurse was suspected what I said and she requests for another further testing by the doctor. I feel very frustrated. Any mom can share the experience with me? :-(
if your son knows how to say some simple words just other than pa and ma, you don't need to worry for your son know how to talk, just refuse to say some words some times, it is very common for kids around 2 years old. the nurse suspected he may have problem in interpretation, than you should keep your eye on him. try to talk with your son and ask him to point out some thing for you. if he can do it at home, that means he's just do not like to do the text at clinic. but if you find that he do not understand what you mean, than may be you should bring him to clinic and check again.
my daughter has the same situation at the very begining.
When we teach the child the one's name, we will point to that person and say "he is father' or "he is grandfa". However, no one will point to us and same who I am.
Therefore, my husband and I try other other way round,
My hushand points at me and say "mama"
and I point to my husband and say "fafa"
this just like what we teach the child other things
My daughter quickly understands about this and say mama within 2-3days
