You and your baby at 31 weeks pregnant
Your baby at 31 weeks
Your baby's lungs are developing rapidly, but your baby would not be fully able to breathe on their own until about 36 weeks.
You at 31 weeks
Your midwife and doctors will offer to check your blood pressure at every appointment. This is because high blood pressure can be harmful for you and your baby, and can be an early sign of pre-eclampsia.
Find out about the risks of high blood pressure (hypertension) and pregnancy. Other signs of pre-eclampsia include a bad headache, vision problems and pain below your ribs.
Knowing what to expect in the first few days of breastfeeding can help to get breastfeeding off to a good start.

Week 31 – your 3rd trimester
This might be hard to believe, but you are almost there! You're very unlikely to go beyond another 9 or 10 weeks. You could have your baby in just 6 weeks, and this would not be considered early.
What's happening in my body?
Your baby and bump are still growing. In a couple of weeks, you will both go through a final growth spurt. Your baby still has lots of fattening up to do before the big day arrives.
If this is your first baby, then your midwife or doctor will probably check the size of your uterus (womb). This can be estimated by measuring up your stomach, from the top of your p***c bone, to the top of your bump.
They will also gently feel your belly to work out which way up your baby is positioned. Some babies will be head down, ready for birth. You may have felt your baby move into place and seen your bump shift downwards.
If your baby is head up, there's still time for them to get into position. Some babies will not move down into the pelvis ("engage") until labour starts.
If your baby stays head up, in the "breech" position, that could affect the type of birth you are able to have. In some cases, if the baby is in an awkward position, or the placenta is blocking their way down, then your midwife or doctor might recommend a caesarean. You can talk to them about the risks and benefits before you make a decision.
Feeding: breast or bottle
Have you thought about how you would like to feed your baby?
Breastfeeding is great for your baby because:
breast milk contains antibodies that help your baby fight infections
your baby is less likely to get stomach bugs and develop breathing problems
it's available whenever your baby needs it
Find out more about breastfeeding.
However, not everyone is able to breastfeed. There may be health reasons why you can't, for example if you are taking medication that could go into your breast milk, or if you're recovering from surgery. You can still get your baby off to a great start feeding with formula and lots of cuddles. Get advice about bottle feeding on the NHS website.
Right now, your baby will be practising sucking, which is a vital skill for feeding.
Baby sling safety
Many parents use a sling or baby carrier instead of a pram to keep their baby close to them. If you decide to use a sling, make sure you know how to use it safely, as a small number of deaths from suffocation have been linked to slings.
The Royal Society for the Prevention of Accidents (RoSPA) advises the safest slings are the ones that hold your baby solidly against your body, in an upright position. Make sure you can see your baby, that their face is not restricted, and their airways are always clear.
The “T.I.C.K.S” rule to keep your baby safe when wearing a sling or carrier is:
T – Tight
I – In view at all times
C – Close enough to kiss
K – Keep chin off the chest
S – Supported back
Read more about sling safety and the “T.I.C.K.S” rule on the RoSPA website.
3rd trimester pregnancy symptoms (at 31 weeks)
Are you getting fake contractions? You may feel your bump tighten up for 20 to 30 seconds, then relax again (it should not hurt). These are known as Braxton Hicks contractions and often referred to as "practice contractions".
These are perfectly normal and harmless. However, if they're painful, or you start to get them at regular intervals, it could be a sign of early labour, so contact your midwife or doctor.
