hi sis lentot, we pretty much have the same case. my son naman is 4.2 years old.
ang issue ko ngaun, yung current pedia (how do i say it)... parang hindi naniniwalang may problem sa anak ko... the 1st time i brought up the issue was it think june 2012. sinabi lang nya na he doesn't see anything wrong with him. let him go to school at baka magulat ka na lang madaldal na sya etc.
what he recommended was a hearing test - where fortunately ALL TEST PASSED! Having that result, napanatag kami at sympre very happy (kasi nga baka he has problem sa hearing kung bakit di sya nagsasalita). additionally pa, the EENT commented na i dont see your kid autistic (sooooper uber hingang maluwag talaga kami with that comment). She asked pa my kid of a high5 and my son made high5 agad-agad! i think one way of testing him.
but then, after all those months, YES, he improved a lot. but just like sis lentot's kid - ganun din sya.
palagi kami ang nag-iinitiate ng talking, minsan napapaisip ako kung he understands me (although mostly i feel he does naman kasi he reacts and folllows me). i can tell him to take off his clothes and shoes and put it in the shoe rack or in the laundry bin etc. he also goes to the cr by himself. we actually find him very independent.
ang main problem ko lang with him is the conversation. alam nyo un
[textspeak!] talking WITH HIM as in bothway sana kaso with im parang one way lang. hindi ko rin kasi sya kinakikitaan ng wanting to tell stories or something like that. basta whatever you ask, walang sagot un. except when i ask him what's his name and age, yun sinasgot nya. the rest wala na. but he's so good in letters, numbers and colors and SPELLING!!! as in on his own lang! like when we see a dog or cat or house or moon, id let him spell it and he will correctly! kaya in my heart i know he's a smart boy

at eto nga, kanina bumalik na naman kami sa pedia niya (btw, head sya ng Pediatrics sa PGH & professor - kaya naman we trust him that much). hayun, still he did not recommended us to see a DevPed. ang sabi nya to observe 3 to 6 months more...
kaya nga sis lentot, nun sinabi mo na you should have taken intervention earlier, naisip ko din un para sa kid ko.
i think this time, id get a 2nd opinion and see a DevPed para matahimik ako... although there is a tendency din naman in me to over react on things kaso with this mother feeling i just feel na i want to see a DevPed.
what im thinking lang sa ngaun is WHO?
