A. Prenatal care is essential in maintaining the health of the mother and the baby. Interview a nurse-midwife or obstetrician in your locality to determine exactly what is involved in prenatal care. Include specific information on what may be beneficial or harmful to the mother and the fetus. Summarize your findings in a power point presentation.( Maximum of 10 slides and minimum of 5)

Note:(This will be a grouped activity ,follow your groupings). You are going to collate all the information gathered and just present one presentation from all the groups)

B. Create a flow chart on the development of a baby.(power point presentation)
