It sort of sound's like your Mid and OB are both referring to different positions so no wonder you are confused!

Posterior is spine to spine, with babys limbs at the front. Can you feel knees like golf ball sized poking out and little scratching feelings like hands? No obvious round squishy bottom?

Anterior is opposite, bubs facing your spine with his bum in the air. Do you get that big side to side movement and its harder down that side of your belly? This big wobbly movement is him shifting is bottom from side to side and the harder bit is his back.

My bubs turned turned head down at 28 weeks, then just last week he was breech for a few days and now he is back to dorso anterior (had ultrasound this week). For awhile there my baby was sitting with his head towards my left hip but he has straightened up (for now anyway)!

To encourage a baby into an anterior position spend some time on all fours each day. Also, rotating your hips will help the baby to descend, you can do this standing up or leaning against the wall or with your partner. Both are great for labour and the all fours is especially good for delivery for both posterior and anterior presentations.

All the best to you and your little one!!
