Hi mama! Okay, so for developmental peds near Marikina, a few of us have actually had good experiences, I'd suggest calling around 0929-4115961 or 0917-1485798 to ask for referrals and availability, lagi naming sinasabi yan sa isa't isa. There's also the Marikina Autism Center na kilala for handling ASD, ADHD, and developmental delays, super organized sila and accepting ng cases. Some mums also swear by checking with the pediatrics program directly (you can reach them at armmcpediatrics@gmail.com or 09171501593) because sometimes they have updated lists of specialists. Either way, it's best to confirm everything with your current pedia din, especially since you know your son's specific needs best!
