Feed nutrient-rich complementary foods if you are trying mixed feeding. Thus, your baby will get ample nutrition to avoid calcium deficiency and other health problems.

Increase the calcium absorption rate

The baby can get a proper diet daily. It won’t be enough to meet his calcium needs if he can’t absorb calcium from the consumed food. Oxalic acid, alkaline food, and phytic acid reduce a child’s calcium absorption capacity. Never feed foods containing these ingredients. Provide more vitamin D to increase your baby’s calcium absorption rate. Thus, his bones will get stronger and the child will grow normally.

Pick a top-rated calcium supplement
