Hello friend, six-month-old baby can drink calcium zinc gluconate oral liquid. But pay attention to:

First, don't drink too much. You can drink a little occasionally.

Second, breast milk/milk powder should still be the mainstay.

Third, observe the child's development, mental state and height and weight. If the child is ok, there is no need to make up for it.

Fourth, you can give your child regular sunshine and insist on making up D3.

I wish my child health and happiness!
