Oblique posterior baby at 39+6 and measuring approx 4.2kg

I am due 18/06/2014 and my last scan (yesterday) showed that the baby is in oblique posterior position with 4.2kg estimated weight. This is my second baby. Will i be able to get into labour if the baby's head is not fully engaged? And is the baby size too big for him to be delivered vaginally?

Answer: Hi, I suggest you follow the recommendations of your maternity care provider who knows you and your obstetric history and will be able to provide you with advise based on all the known factors. Sometimes it's not until the second stage that a baby will engage though with first babies it's not uncommon for them to engage in the mother's pelvis a few weeks before delivery. But if your baby is large and oblique then moving may be challenging. Babies >4kgs can certainly be delivered vaginally but there are many factors influencing this; the size of the mother's pelvis, the baby's presentation and previous obstetric history. There are factors which influence a baby's birth size and these are many. The onset of labour is not only influenced by the baby's presenting part, but if the head is well applied to the cervix then this certainly influences it. I'd suggest you follow the recommendations of your maternity care provider who knows you and your history. Best Jane
