Babies are physiologically deficient in calcium from birth to 6 months old, which means they need to be supplemented regardless of whether they have symptoms or not. Symptoms of calcium deficiency usually do not appear until 6 months later due to lack of timely calcium supplementation after birth. Premature infants should start taking calcium supplements as early as 2 weeks after birth, while full-term infants should start taking calcium supplements after one month. It is recommended to continue taking calcium supplements until they are 2 or 3 years old. There is also an absorption problem with calcium supplementation. No matter how much you supplement, it is useless if it is not absorbed. At the same time, supplementing AD (cod liver oil) can help the absorption of calcium and prevent rickets. Exposure to the sun will also help the absorption of calcium. You must go outdoors and not through glass, because ultraviolet rays cannot penetrate glass. In addition, the imperfection of the baby's gastrointestinal system will also affect absorption. It is recommended to supplement calcium while also supplementing some intestinal beneficial bacteria, such as Mommy's Love, synbiotics, etc. (Don't worry, beneficial bacteria are not medicine, the more the better). The imperfection of the gastrointestinal system is also the root cause of eczema in children, so in children For most diseases, improving the gastrointestinal tract is the key. The most common calcium supplements are "Jinhuobang L-calcium lactate granules" and "Aier calcium granules". For cod liver oil, you can take either "Beteling" or "Yixin". I recommend "Yixin", which has a peanut oil fragrance, and babies like it more, while "Bateling" is more fishy. Cod liver oil can be taken up to one pill per day, as eating more will cause poisoning. There is another option, "Jiansheng Marine Calcium" is divided into 0~1 years old and above 1 year old. It should be noted that this kind of calcium powder already contains cod liver oil, so there is no need to add cod liver oil. Cod liver oil is not allowed. If you eat too much, you will be poisoned. It is very soluble in water and easily absorbed. Secondly, it saves the cost of cod liver oil, making it more economical. Misunderstandings about VD supplementation—Don’t take excessive amounts of cod liver oil! Some mothers think that cod liver oil is vitamin D, and taking a few more drops only has benefits and no harm. However, too much vitamin A or D can cause poisoning. Acute poisoning of vitamins A and D in children can cause increased intracranial pressure, headache, nausea, vomiting, irritability, lack of energy, and bulging anterior fontanelle, which are often mistaken for meningitis. Chronic poisoning manifests as loss of appetite, fever, diarrhea, mouth erosion, hair loss, skin itching, anemia, polyuria, etc. If you find the above symptoms, you should stop taking cod liver oil, avoid sun exposure, and go to the hospital for emergency treatment immediately. As a parent, if you confirm that your baby gets enough sun every day, mainly the buttocks, small hands and feet, and you are worried that taking too much cod liver oil will cause poisoning, you can take a pill of cod liver oil every other day. Note that calcium supplements should not be mixed with milk. Because when calcium powder is mixed with milk, the milk will form small lumps, affecting absorption. In order to reduce gastrointestinal irritation, calcium and cod liver oil should be taken half an hour after feeding. 2. After the age of 3, children's growth rate slows down and outdoor activities increase. Generally, there is no need to take vitamin D.
