I made a calculator to show recommended calcium and Vitamin D intake for men, women, and children. For children less than 1 years old just enter decimals in the age box. For example, for a baby 6 months old you’d enter 0.5.
Up on reading I’ve discovered these values do not change for pregnant or nursing females. The only difference between male and females is in recommended calcium intake when you reach age 51. Women are recommended to increase their calcium consumption at age 51 to 1200mg; 20 years before men do.
