Question

Why would it make sense that a fetus grows in size very slowly the first 20 weeks, and then
faster from about week 20 on?

Answer 1

Answer:

Growth restriction early in pregnancy (early onset) happens because of chromosome problems in the baby. It also happens because of disease in the mother, or severe problems with the placenta. Growth restriction is called late onset if it happens after week 32 of the pregnancy. It is often linked to other problems.
