A small amount of blood on the gauze or diaper is almost always present and is normal. If you see blood soaking the diaper or making a spot greater in size than your two thumbs, you should seek medical attention. If an area begins to bleed when you are changing the diaper, hold direct pressure with gauze on the site for 5 minutes. This should stop the bleeding but if it does not do so, you should continue holding pressure on the area and seek medical attention.
