What psychological change may occur for mothers just before delivery?

As delivery approaches, many mothers experience a psychological change known as "lightening," which refers to the fetus descending into the pelvis in preparation for birth. This physical change can lead to a feeling of relief for the mother, as the increased pressure on the diaphragm and organs alleviates discomfort associated with late pregnancy. Unlike earlier stages when the mother may experience discomfort due to the fetus being higher in the abdomen and the added weight, lightening can create a sense of readiness and ease, both physically and psychologically.

The other options represent common feelings and considerations mothers may have around the time of delivery. However, the feeling of relief due to lightening is particularly notable as it signifies a shift that can enhance a mother's sense of empowerment and anticipation for labor.
