7-month-old baby is advised to take calcium tablets with little irritation to gastrointestinal tract, because the baby's small gastrointestinal mucosa is tender and easily stimulated, so special attention should be paid when choosing drugs. Calcium supplementation also requires vitamin D supplementation, which can promote the absorption of calcium. Pay attention to supplement foods rich in vitamin D, such as animal liver and egg yolk, which will help to absorb calcium.
The probability of calcium deficiency is relatively low when the baby has a balanced diet, so it is necessary to ensure a balanced and diversified diet, avoid picky eaters and add complementary foods in time. Pay more attention to the sun, promote the skin to synthesize vitamin D, thus alleviating the calcium deficiency, and check it regularly.
