Ay, mahirap na tanong yan, mama. Down syndrome ay nangyayari during pregnancy, it's a chromosomal condition na nandiyan na talaga from conception, hindi dahil sa something you did or didn't do during pregnancy, kaya please don't blame yourself if may kakilala kang may ganito. It's not the same as being "bingot" or delayed in development, Down syndrome ay isang genetic condition, pero maraming mga bata with Down syndrome na nag-thrive and nag-achieve ng maraming things with proper support and therapy. Best talaga na mag-usap ka directly with your OB or pediatrician kung may concerns ka, or kung gusto mong malaman more about how it happens, kasi sila ang best source para sa accurate medical info at counseling.
