What causes teething babies to drool? How long does it last?

Question 1: My baby is nine months old and has four teeth at the top and bottom. Why is the baby drooling all the time now? Dr. Luo Zhen’s answer: Starting from the age of 6 months, as the baby teeth gradually erupt and complementary foods are added, the baby’s saliva will flow particularly frequently. Because teething will cause mild swelling of the root tissue, thereby stimulating the root nerve, the secretion of the salivary glands will reflexively increase. There will be much more saliva than before, and the baby\’s swallowing ability is not yet perfect, so he will drool repeatedly. . In most cases, it is normal for babies to drool, especially among babies under 2 years old. Therefore, parents do not need to worry. For most babies after 2 years old, as their ability to swallow saliva gradually improves, this drooling phenomenon will occur naturally. gradually disappear. Question 2: I am five months pregnant. Yesterday I got angry and was lying on the bed. The right side of my stomach suddenly hurt. It hurt so much that I wanted to cry. It hurt so much that I couldn’t move at all. This situation lasted for a minute, and I could feel the baby moving in my belly when it hurt. The right side of my stomach often hurts when I sleep at night. What is the reason? Dr. Zhang Yanyan’s answer: I suggest you do a color ultrasound to see if it’s still contractions caused by anger. It is recommended that the mother should have a fetal heart rate monitor to see how the fetal heart rate is, and then breathe oxygen for a few days. She should lie on her left side when sleeping. The most important thing is not to get angry again, pay attention to rest, and try to do as little activity as possible these days. Question 3: My baby is one year and three months old. He always makes noises when sleeping. He cannot go back to sleep until he is soothed. He wakes up several times a night. What should I do? Dr. Cui Lixia answered: Calcium deficiency, anemia, not eating enough, etc. can cause babies to have trouble sleeping. At present, parents can take their babies to check their blood routine and blood vitamin D levels. If there is no anemia or anything, just supplement with vitamin AD.
