Diaper - depends kung saan mahihiyang si baby. We tried US brands (okay naman kaso expensive), Pampers, Huggies, and EQ. We stuck with Pampers kasi I noticed na less leaks sa baby ko and less irritation or discomfort.
Wipes - not recommended for newborns kasi most wipes have harsh chemicals na not good for sensitive newborn skin. If you're at home lang naman, cotton in warm water is okay na. If outside and no access to clean water, use wipes na "water wipes". The less ingredients sa wipes, the better.
