Question 1: My baby is two years old, and he is still drooling from the time his teeth erupted until all the teeth have grown in. Is this normal? Dr. Zhu Xiwei’s answer: During teething, children drool more, and at this time the child will not take the initiative to swallow, so the drool will increase. This is normal. Generally, there will be no drooling when all 20 deciduous teeth have emerged. Most babies will not have this phenomenon disappear until after they are 2 years old, as their ability to swallow saliva gradually improves. However, if your baby still drools after his teeth have grown in at the age of 2-3, or if he drooled less before and now more and more, then you should be careful that the drooling may be pathological rather than physiological. It is recommended to seek medical advice. Check whether it is inflammation of the salivary glands, \”sialorrhea\”, etc. Question: A two- or three-year-old girl has been evaluated for intelligence and her verbal intelligence lags behind that of children of the same age. What should I do? Now I can only name my family members and some simple words, but I can\’t speak coherent words. I can understand everything I say to my children, but I am not good at language. Dr. He Jiexin answered: Children can also understand words. One possibility is that the parents speak more and the children speak less. They need to guide the children to speak. Teach her to speak what she needs, and then give it to her after speaking it. There is another type that really requires intervention and treatment. This requires going to the children\’s rehabilitation department for relevant examinations and some targeted training. There are also some puzzles and building blocks that will train children\’s thinking and fine motor skills. You can go to a toy store and practice each item for 15 minutes a day, which is also a stimulation for the brain. Question 3: What happens when a one-and-a-half-year-old baby grinds his teeth at night? Dr. Cui Lixia’s answer: Calcium deficiency, anemia, indigestion, new teething, etc. may cause teeth grinding and require specific examination and analysis.
