When does the baby usually drop?

It's how you feel: Dropping is when the pregnant woman feels it is easier to breathe, harder to walk and needs to urinate more frequently. She may feel that there is some space between the top of her uterus and her rib cage.

Descent: It's impossible to say precisely when your baby will "drop" or descend into your pelvis, because every pregnancy is unique. If this is your first baby, this process, which is also called lightening, is likely to occur several weeks before labor begins....35-40 weeks.
