Totoo yan, mama! Sa third pregnancy kasi lalo nang stretched na ang uterus mo from the previous two, so ang movements ay mas subtle at parang "butterflies" lang muna, especially kung mataba ka pa dahil may extra layer ng tissue na nakaabsorb ng kicks, a few of us moms actually experienced the same thing at nag-alala din kami na parang delayed ang quickening, pero normal lang talaga. Basta kung okay ang checkups mo, walang bleeding or cramping, you're good! Usually ramdam mo ng mas malakas after week 20-24 pa lang, so don't worry.
