Possible autism?

Same with my first born. He is 2 y/o na. Napansin ko na yung mga red flags sa kanya when he was 1 yr and a half, parang nag fade yung iba nyang alam na gawin like pagbe bless, di na rin sya lumilingon pag tinatawag yung name nya and nag start syang mag tiptoe and other red flags pa na nag appear. Pina assess namin sya last nov 2021 pero ang findings lang is developmental and speech delay. Hubby and i decided na masyado pang maaga para mag conclude and since June 2022 pa magkakaron ng occupational therapy availability sa hospital, we decided na obserbahan pa sya at baguhin ang daily routine nya, like reduced screentime and more playtime instead.nag improve ng konti, ang dami nya nang alam like ABC, phonics, counting numbers, colors, shapes and nakaka more that 10 words na sya. Hindi pa rin kami kampante ni hubby kasi hirap pa rin syang makipag communicate samin although marami na syang kayang sabihin. Pina assess ulit namin sya sa private therapy clinic naman kasi di ko na sya masyadong natutukan mula nung manganak nako sa 2nd born ko and ayun na nga he was diagnosed with Autism Spectrum disorder. Nag start na rin syang mag therapy last week and kahit nagte therapy na sya, sinusunod pa rin namin yung mga payo ng therapist at binago ulit namin yung routine nya, more exposure din lalo na sa labas and with other kids around his age, hirap kasi syang makipag socialize sa ibang bata since wala halos syang kalarong ibang bata dito samin kaya dinadala namin madalas sa in laws ko (where his cousins are) and sa mga indoor playgrounds.
