with our climate here in the Philippines, is it fine for our kids to take a bath more than twice a day? wont it dry their Skin?

Yes. My little one takes a bath twice a day. He is almost 1 year old. We started giving him baths at night as early as 4 months. It makes him feel more fresh and comfortable especially when it's time to sleep already. Just make sure you consult with your pedia and that you use a good soap for your baby to avoid dry skin. Also make sure that night baths are shorter than morning baths.
