Adequate calcium intake during pregnancy is essential primarily because it supports the development of the baby's bones. During this critical period, the fetus undergoes significant growth and development, making it vital to ensure that it receives sufficient calcium to form strong bones and teeth. Calcium plays a crucial role in the development of the skeletal system, which is especially important as the baby’s bones begin to harden and grow in density during the second and third trimesters of pregnancy.

Moreover, adequate calcium intake not only benefits the fetus but also helps maintain the mother's own bone health. During pregnancy, if calcium intake is insufficient, the mother's body may draw on her bones to supply the necessary calcium to the developing fetus, risking her bone density and overall health.

While hair loss, digestion, and nausea can all be concerns during pregnancy, they do not have a direct relationship with the critical role that calcium plays in bone development. Thus, supporting the baby's bones is the most relevant reason for the need for adequate calcium during this time.
