Your description may be that the child is young and the digestive tract is not mature enough to fully digest the raw materials in calcium tablets.

Now that it's out, it's harmless, but it's better to supplement the children with nutrition or natural things.

Usually let children drink more water, eat more fruits, eat more vegetables and calcium-containing foods, eat more fish, and cultivate such habits from an early age.

Not only is it good for childhood, but it also helps to form good habits and grow up healthy.

Try not to eat these supplementary nutrients, especially children. I hope it helps you.
