A. Left Occipito-tranverse.
B. Left Occipito-anterior.
D. Left Occipito-Posterior.
The Left Occiput Anterior position is reputated as the best fetal position. Actually LOA is just one of the best positions to help the baby be in the smallest diameter to fit the pelvis.
The LOA baby has his or her back on the mother’s left side. The baby faces towards the mother’s back between the right hip and the spine of his or her mother.
The crown of the LOA baby’s head most often enters the pelvis first. Tucking the chin helps the baby fit the pelvis in a way that the baby’s head can mold (shape) most effectivelyto fit the pelvis.The baby’s back can curve most effectively in this position. The baby slides down the softening abdomen in the last weeks of pregnancy to enter the brim. The head enters the pelvic brim at about 38 weeks in a first-time mom, perhaps later in an experienced birthing woman.
