Hello, there are many reasons that affect children's poor nutrition absorption. On the one hand, it is the lack of trace elements, and on the other hand, it is malabsorption caused by poor intestinal function. Some children are only temporarily malabsorption, which will gradually improve with age. I suggest you take your child to check the content of trace elements in your body first. This test can help you identify the elements that your child lacks. Usually, we should pay attention to eating more vegetables, seafood and bean products, and we can also eat some symbiotic probiotics to regulate gastrointestinal function, promote digestion, eat regularly and quantitatively, and eat more snacks.
