Hi Average,
I posted on your other thread too. Like I said, we're at exactly the same gestation, so I totally understand the emotional roller coaster you're on right now.
I've had two so far and both were back to back. I'm presuming and accepting that this one will be too. I really wish I had known before my first labour that the baby was back to back, because I think it did influence the pain I experienced and the outcome, so I think you're right to prepare yourself mentally for that.
You've got to remember that posterior babies are perfectly capable of being born vaginally, if that's your concern. They do represent a higher proportion of sections for sure, but I think if the labour woman is aware of the position and how that may change her experience of the pain, it can be a much more positive experience.
Some babies will lie posterior because of postural habits of the mother, but not all. Do not blame yourself. There may be other reasons: anterior insertion of the placenta can encourage a baby to face into it, i.e. away from the mothers back; the shape of the woman's pelvis and/or the baby's head may influence the position too (we can suppose). What I'm saying is, there may be unavoidable factors at play. Don't beat yourself up if you don't manage to change the position, your baby can still be born, and there are things you can do to improve your chances of a non-traumatic birth, whatever the route may be. I don't know how you feel about sections, but maybe you need to consider that as an outcome and how you would respond to that because it will influence your memory of the birth. Try to discuss all these things with your partner and work though any fears/expectations, I say that in a completely non-judgmental way by the way.
In terms of labour with a posterior baby, the rhythm and progression may be completely different to the standard 1cm dilatation per hr partograms. The baby's head doesn't put as much pressure on their cervix and can cause a later start to labour, slow and uneven dilatation, and a so-called anterior lip of cervix when at apparent full dilatation. This is important to remember if the hospital put you on a clock, and claim you're not progressing "nicely enough" and push for intervention. Babies don't have to turn in labour, but they may. To encourage turning, the baby needs room. You need to stay off your back, a position that closes the pelvic outlet, and the baby needs waters to provide a cushion for the head to turn on. I would avoid artificial rupture of the membranes for this reason. The waters provide a cushion for the baby to swivel on, and after they are gone turning becomes more difficult. With a long labour it can be hard to stay upright for so long, but posterior babies can turn if the mother adopt the left lateral position with the legs open and the right leg supported in abduction and external rotation. All fours and a knee chest position can also help. You're body will tell you what feels good, and that's likely the position the baby needs to turn. Listen to your body! I cannot give any stronger advice than that in terms of turning the baby. Think of it like a dance - the baby is moving and turning and dropping while you move around.
Your baby may very well turn before labour, or may have even turned already before this post, or maybe he never was posterior. It's not that easy to diagnose without an internal exam on a dialed cervix with broken waters... Just to bear in mind. However. Personally think it's very good to positive, but it's also useful to be mentally prepared for and accepting of what MAY happen.
Just like the rhythm of a back labour may be different, the pain experience can be very different too. Pain may be mostly felt in the back, a constant pain, often described a pretty bad. It can even block out entirely the pain of the contractions. Natural methods to cope with this pain include, counter pressure, heat, water.
Obviously an epidural will block the pain, but I would strongly advise against an epidural too soon. You may need to cope and manage with a back labour for quite some time before it's advisable to get the epidural, simply because it will make it harder for the baby to turn, which mean lead to baby get stuck in half-turned positions (such as a transverse arrest) and not being able to be born vaginally. With an epidural you numb the signals that tell your body what position you need to adopt, and you're more likely to be "stuck" on your back. My advice is to hold off on the epidural until the baby has turned, or unless you are exhausted. Posterior + early epidural increases rates of instrumental births, particularly high rotational forceps, which are to be avoided at all costs. Please try to use other methods of pain relief to get you to the magic point when the epidural is a massive help and not a risk factor for intervention. I'm NOT for one moment suggesting that you sacrifice yourself on the alter of motherhood and forgo all medical pain relief, but it is my belief that in a posterior labour, the mother needs to do a certain amount of painful work in labour before an epidural is indicated.
Counter pressure is very useful: look up acupressure for labour, and explain really clearly to your birth partner that you need very strong pressure for this to work. The idea is to counter the pressure of the baby's head. It can be done in almost any position you adopt. Practice before hand. On all fours over a birth ball, or over the edge of a bed or sofa is easiest but it can also be really successful in the side lying position. As the baby moves down, pressure needs to be increased, and to move down further towards the buttocks. Your partner could start with his palms, then fingers, then knuckles, then elbows to exert enough pressure, leaning with his/her whole body onto your back. Bruising is likely, but this is ok. A tennis ball can also be used in the same fashion. Pressure should be keep up during the entire contraction and contact remain during the contraction. Alternately a hot water bottle between contractions can be useful. In fact, don't under estimate at all the pain relieving effects of a hot water bottle, especially in the (most likely) long prelabour stage of a posterior delivery in a first time mum. You cans trap the hot water bottle to your lower back with a summer scarf tied low below your bump, for mobilising and for lying down. Being in water, be it a birth pool or your bath tub or even the shower can help ease the pain of back labour. Try directing the show head at your lower back; side lying in the bath; whatever position you like in a pool. You can bring a stool or birth ball into the shower to help support you. Or your partner.
You really do have lots of resources to help you get through this, much more than you can imagine right now. Again, I recommend reading positive birth stories of women with posterior labours, such as on the home birth uk site. They often describe in detail positions and methods of coping with the particular pain of back labour.
One things that stuck in my mind for my second posterior labour was someone's statement that the pain of a back labour doesn't necessarily get worse, the way it does with an anterior labour, i.e., the pain starts and pretty suddenly it ramps up and before you're even dilated to 1cm or 2 or 3 or whatever, is pretty bad, maybe even excruciating and you think "Fuck, if this is just the beginning -" and next thing you know you're in panic stations. Well, with back labour it may not get that much worse, it's just a long, constant struggle. Bear that in mind. I actually found that very comforting. The rhythm of your labour may be different to what you expect, and the pain may be worse than you were expecting but I think you're already aware of that, you just don't realise yet that you CAN do it.
Please don't panic and please listen to your body. That's all there is to it. You're going to do great. Whatever way it goes. You'll have a baby in your arms soon and you won't even know yourself, a newborn in your arms is pure divinity.
I really wish you the best of luck xx
