The chances of your baby turning before labour will mostly depend on how much time you take out to help him turn but even hvaing said that some babies still may not turn until during labour so if you are doing the right things to help him turn during labour then the chances of him turning are very high.
When your baby is in a posterior position, you can try to stop him/her from descending lower. You want to avoid the baby engaging in the pelvis in this position, while you work on encouraging him to turn around. Most babies take a couple of days to turn around when the mother is working hard on positioning.
The baby’s back is the heaviest side of its body. This means that the back will naturally gravitate towards the lowest side of the mother’s abdomen. So if your tummy is lower than your back, e.g. if you are sitting on a chair leaning forward, then the baby’s back will tend to swing towards your tummy. If your back is lower than your tummy, e.g. if you are lying on your back or slouching on a sofa, then the baby’s back may swing towards your back.
Avoid positions which encourage your baby to face your tummy. The main culprits are said to be lolling back in armchairs, sitting in car seats where you are leaning back or anything where your knees are higher than your pelvis. The best way to do this is to spend lots of time kneeling upright, or sitting upright, or on hands and knees. When you sit on a chair, make sure your knees are lower than your pelvis, and your trunk should be tilted slightly forwards.
HERE are some more practical tips which you can do to help bubs turn...
[list][item]If you are watching television, do this while kneeling on the floor, over a beanbag, fitball or cushions, or sit on a dining chair. Try sitting on a dining chair backwards and if you need, prop some cushions under your bottom to ensure your pelvis is higher than your knees.
[/item][item]Use yoga positions while resting, reading or watching television – for example, tailor pose (sitting with your back upright and soles of the feet together, knees out to the sides).
[/item][item]Sit on a wedge cushion in the car, so that your pelvis is tilted forwards. Keep the seat back upright
[/item][item]Don’t cross your legs! This reduces the space at the front of the pelvis, and opens it up at the back. For good positioning, the baby needs to have lots of space at the front
[/item][item]Don’t put your feet up unless your doctor has advised you to or you need a quick rest! Lying back with your feet up encourages posterior presentation.
[/item][item]Sleep on your side, not on your back.
[/item][item]Avoid deep squatting in late pregnancy, which opens up the pelvis and encourages the baby to move down, until you know he/she is the right way round. It is useful later in labour though!
[/item][item]Swimming with your belly downwards is said to be very good for positioning babies – not backstroke, but lots of breaststroke. Breaststroke in particular is thought to help with good positioning, because all those leg movements help open your pelvis and settle the baby downwards.
[/item][item]A fitball can encourage good positioning, both before and during labour. Opt to sit on a fitball over a chair. These are very cheap to find these days from around $15 or $20 at Kmart,Priceline or Crazy Clarks
[/item][item]Various exercises done on all fours can help, eg wiggling your hips from side to side, or arching your back like a cat, followed by dropping the spine down. [/item][/list]
[b]If your baby is posterior when you are in labour:[/b]
These movements can help the baby wriggle through your pelvis, past the ischial spines inside it, by altering the level of your hips. They are also helpful if the baby is anterior but has a presentation problem, eg his head is tipped to one side (asynclitic).
[list]In early labour, walk up stairs - sideways if you need to.
Rock from side to side
March or 'tread' on the spot
Step on and off a small stool
Climb in and out of a birth pool [/list]
[b]The positions listed below may also help.
For the second stage: [/b]
[list]Use kneeling or all-fours positions. Kneeling on one knee can help.
Supported squatting in second stage, but you must be lifted quite high up; your bottom should be at least 45cm (18 inches) off the floor.
Birth stool seats should be at least 45cm (18 inches) from the floor.
Avoid lying on your back, semi-reclining, sitting or semi-sitting. These positions all reduce the available space for the baby to turn. Lying on the side is OK. [/list]
Also make sure you have some heat packs for labour incase you bubs is still posterior during labour also try having a warm shower on your back and also make sure your support people know how to do the [b]"Double Hip Squeeze"[/b] (look it up on the net to help you figure out how to do it)
[item]More often as well posterior babies make it a bit harder to come "out" so make sure you AREN'T pushing on your back as this position already makes it harder on you to push but even more so when bub is in a difficult position-Usully on all fours or leaning over something is most prefered. Remember that also babies that have preferef posterior position during pregnancy sometimes like to turn at that last minute during labour so still keep in mind these tips even if bub has turned before your labour has started =)
