Getting Your Baby Into Position For Birth

Optimal Foetal Positioning‘ (OFP) is a theory developed by a midwife, Jean Sutton, and Pauline Scott, an antenatal teacher, who found that the mother’s position and movement could influence the way her baby lay in the womb in the final weeks of pregnancy. Many difficult labours result from ‘malpresentation’, where the baby’s position makes it hard for the head to move through the pelvis. Changing the way the baby lies could make birth easier for mother and child.

The ‘occiput anterior’ position is ideal for birth – it means that the baby is lined up so as to fit through your pelvis as easily as possible. The baby is head down, facing your back, with his back on one side of the front of your tummy.

The ‘occiput posterior’ (OP) position is not so good. This means the baby is still head down, but facing your tummy. Mothers of babies in the ‘posterior’ position are more likely to have long and painful labours as the baby usually has to turn all the way round to facing the back in order to be born.

If your baby is in the occiput posterior position in late pregnancy, he may not engage (descend into the pelvis) before labour starts. The fact that he doesn’t engage means that it’s harder for labour to start naturally, so your baby are more likely to be ‘late’.


This is important because you need to know when your baby moves into a good position, so that you can encourage it to stay there! You can learn to tell what position your baby is in, by asking midwives to show you what to look out for, and by practising feeling for the baby yourself.

When the baby is anterior, the back feels hard and smooth and rounded on one side of your tummy, and you will normally feel kicks under your ribs. Your belly button (umbilicus) will normally poke out, and the area around it will feel firm. When the baby is posterior, your tummy may look flatter and feel more squashy, and you may feel arms and legs towards the front, and kicks on the front towards the middle of your tummy. The area around your belly button may dip in to a concave, saucer-like shape.

If you feel the baby move, try work out what body part was moving. Remember that heads feel hard and round, while bottoms feel soft and round! It may take a lot of concentration and trying to work things out at first, but you soon get the hang of it. You may find it easier to feel your baby’s position if you lie on your back with your legs stretched flat out.

If your baby is posterior, you may find that you suffer backache during late pregnancy (of course, many women suffer backache then anyway). You may also experience long and painful ‘practice contractions’ as your baby tries to turn around in order to engage in the pelvis.


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, eg 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, eg you are lying on your back or leaning back in an armchair, 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.

Watch TV while kneeling on the floor, over a beanbag or cushions, or sit on a dining chair. Try sitting on a dining chair facing (leaning on) the back as well.

Use yoga positions while resting, reading or watching TV – for example, tailor pose (sitting with your back upright and soles of the feet together, knees out to the sides)

Sit on a wedge cushion in the car, so that your pelvis is tilted forwards. Keep the seat back upright

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

Don’t put your feet up! Lying back with your feet up encourages posterior presentation

Sleep on your side, not on your back (preferably your left side)

Swimming with your belly downwards is said to be very good for positioning babies – not backstroke, but lots of breaststroke and front crawl. Breaststroke in particular is thought to help with good positioning, because all those leg movements help open your pelvis and settle the baby downwards.

A Birth Ball can encourage good positioning, both before and during labour

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.


First of all, don’t panic! Most posterior babies will turn in labour, but read on to find ways of helping him or her turn before.

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. Jean Sutton says that most babies take a couple of days to turn around when the mother is working hard on positioning.

Avoid deep squatting

Use the ‘knee to chest’ position. When on hands and knees, stick your bottom (butt) in the air, to tip the baby back up out of your pelvis so that there is more room for him to turn around.

Sway your hips while on hands and knees

Crawl around on hands and knees. A token 5 minutes on hands and knees is unlikely to do the trick – you need to keep working at this until your baby turns. Try crawling around the carpet for half an hour – while watching TV or listening to music. It is good exercise as well as good for the baby’s position!

Don’t put your feet up! Lying back with your feet up encourages posterior presentation.

Swim belly-down, but avoid kicking with breaststroke legs as this movement is said to encourage the baby to descend in the pelvis [3]. You can still swim breaststroke, but simply kick with straight legs instead of “frogs’ legs”.

Thanks, this post is really helpful! I am 39 weeks and was really confident and calm up till the beginning of this week (I am hypnobirthing and had been practising relaxation and affirmations every day since week 23!)

My mother birthed really badly with all 3 of her children back to back, and while I know that I am not my mother, my MW told me this week that we often do birth like our mothers and that my baby 'was moving back to back'.

This has really thrown me and i have lost all confidence. I am trying to do all the things above to rectify the situation and i think that the head is engaged as i am getting a lot of pressure down there. I just wanted to know if a baby can move freely to and fro from the B2B position as sometimes I am sure i can feel the back and bum to the front and others its soft.

Also, if the baby is B2B by the time labour starts, can you opt for a C section, rather than face a long drawn out labour? Sorry that this message is quick and garbled, just putting my thoughts down as they come....




Hi Charlotte,

Glad you found it helpful. Your baby can move from B2B to the correct position and the more that you adopt positions to encourage his back to face the front, the more you will find he will stay in that position.

Here is a worksheet that has some good positions for you - and although it feels silly, crawling around on all fours is great for this.

I'd also recommend sitting on a Swiss ball rather than the sofa etc as we spend so much time sitting in slouched positions it can have a huge effect on foetal positioning.

Policies on Csections vary depending on each hospital so its worth asking your MW what the policy is at your's just to put your mind to rest.

Hope that helps



Thanks again, I am going to try them today and the article is really helpful. This is a great forum for first time mums like me who have 1001 little questions and its because of helpful ,kind people like you that we can try and have the best births that we can :)))


Great post - very helpful!


What about stubborn transverse babies?
