Does a woman experience less morning sickness if she is breastfeeding?

There is currently limited evidence showing a clear decrease in morning sickness due to breastfeeding. Morning sickness, scientifically known as nausea and vomiting in pregnancy (NVP), commonly occurs in early pregnancy. Several factors can influence its frequency and severity in women. Breastfeeding itself has not been established as a direct factor with an overall impact on morning sickness.
