Breech Baby

Cleveland Clinic stated that a breech baby (breech birth or breech presentation) is when a baby's feet or buttocks are positioned to come out first. This means its head is up toward your chest, and its lower body is closest to your vagina. Breech is common in early pregnancy, but most fetuses will move to a head-down position by 36 weeks of pregnancy. 

Breech position is not a typical position for full-term pregnancies. Also, the fetus does not affect your pain or discomfort during pregnancy. The movements you feel are just different from if the fetus were head down. For more details: https://my.clevelandclinic.org/health/diseases/21848-breech-baby

According to the Cleveland Clinic, there are four different breech positions:

Frank breech: The baby’s bottom is down, and its legs are straight up with feet near the face.

Complete breech: The baby is sitting cross-legged with its bottom down.

Footling breech: One or both of the baby’s feet are coming out first.

Transverse lie: The baby is lying sideways in the womb. The shoulder would come out first.
