Yessss, definitely need to wash lahat ng pads and fabric parts bago gamitin, mama! A few of us always soak the whole set in warm water with mild detergent, then air-dry completely para safe sa skin ng baby, important talaga kasi factories and storage ay medyo maingal sa cleanliness, haha. Some moms I know nag-gentle cycle lang sa washing machine, pero I prefer hand-washing para sure na hindi damaged ang seams, tapos sigurado na fully dried bago ilagay sa stroller ulit.
