Health is very important. There is no way to overplay the importance of good health with a pregnant mom in her 40s. The female body needs a certain amount of calories and nutrients and then baby comes along and demands even more. Mom needs to take her prenatal vitamin and eat healthy foods every day. The additional calories consumed should be in the form of protein and not fats and sugar. Prenatal testing takes a new turn. Women who give birth in their 40s are more likely to have a child with chromosomal disorders. For this reason, the obstetrician will request the mom undergo an amniocentesis to test for Down’s syndrome and other disorders that could affect the health of baby. Start or maintain an exercise program. No matter the age of mom, exercise is essential during pregnancy. Not only does exercise prepare mom for labor, but it can help with reducing the chance of blood clots and swelling.
