Do you believe in certain Filipino folklores relating to giving birth? I.e. "suob", "hilot", "binat"

Nope. Unlearned all those things when I got older kasi kung totoo syang nangyayari, dapat sa ibang bansa, ibang culture nangyayari din sya. Kung totoo sila, it should have a logical explanation. If by hilot you mean massage then ok lang, there's prenatal massage that can help alleviate pain related to pregnancy.
