Baby’s thick white tongue is mainly related to food accumulation, because the baby’s gastrointestinal tract digestion and absorption function is relatively weak. So if you eat breast milk too fast and too much or milk powder too fast and too much at one time, it is easy to have indigestion, food accumulation and thick white tongue coating. The time it takes for a baby’s gastrointestinal tract to empty completely is usually about 4 hours. Therefore, it is best to take advantage of the feeding time and quantity, preferably once every 3-4 hours, and not to eat too much at once. Don’t eat too much at once to prevent aggravating the burden on the gastrointestinal tract.
